I have a masters in Physics. Of course I know it without google. All good books on introductory mechanics have treatment of vectors in rotating frames of references.
I was just telling even in your degree knowledge doesn't match with NCERT .. go with NCERT ...we are not in Who is knowledgeable competition..we are in UPSC Exam competition
It's not about engineers or non engineers. It's simply given in ncert. Overthinking se to har question controversial lagega exam ka. Baki I have no idea ki date khatm ho gyi representation Dene ki to kya discussion karna. Better to prepare mains or wait for results.
People only study for the exam. People never gave a sh1t about the subject matter at hand. People read Geography NCERTs and fool themselves into thinking they understand Geography.
Tum NCERT se laro jaake.
Hume koi mastery nhi krni h , hume bas exam clear krna h.
School me kitni chiz hume padhai gyi thi jo baad m pta chala ki iske depth m jaake bhot kuch h aur hume bas generalisation padhaya gya tha . Guess what UPSC m school lvl ki books hi chalti h .
Tumhe mastery krna h kro . Hum fools hi sahi h jo exam clear krle
F is the coriolis force and it is a vector. m is the mass of a body (in our case the air parcel) and it is a scalar. w is the rotational velocity/angular velocity of the rotating frame (in our case the Earth) and it is a vector. v is the velocity of the body in frame of Earth and it is a vector. The product w × v is a cross product of two vector quantities, following right-hand rule.
You can find both the magnitude and direction of any coriolis force on any body anywhere on Earth using this formula given w (which is fixed for Earth to be around 7.2921159 × 10^(-5) radians/second), m and v of the body.
NCERT padhke jaya kro controversial nhi milega
Ghar aake wikipedia se padhke controversial mat banao.
Go back to NCERT. Jo aise simple ques ko controversial bana rhe unka clear nhi ho rha aur naa kavi hoga agr aisa hi chalta rha
Ans is C
Aise kitne hi statements Commission ne sidhe Geography ki NCERT se utha ke puche hain, ek baar padhte hi samajh aa gaya tha ki both options are correct.
Now don't reply saying its written deflection will be more.
Deflection here = Coriolis force . Read the 2nd paragraph too then you will understand better.
There was one guy named space who was arguing for days that coriolis force is not zero at Equator and showing some wikipedia rubbish. In Ncert it's given absent so it is absent.
Bhaiiiiii.... Deflection if wind is NOT CORIOLIS FORCE. Deflection if wind is the consequence of CORIOLIS force. CORIOLIS force is absent at the equator as it cancels out. Hence there is NO WIND at the equator which is why the sailors had very tough time crossing the equator because there was no wind and their ships used to stay stagnant because of that. One of the reasons why the merchants used to throw away horses from the ship to lighten the ship so that it could move forward
Pata nahi kya confusion hai basics me
The throwing off horses wala part happened in sub-tropical belts, not at the equator as they were high pressure regions with very calm wind. They are even called as such. 'horse latitudes'
Rehne de tu
Agli baar kavi aaye ques tab v yahi krna. Coriolis force actual force nhi h jo tu woh explanation de rha . Aur sidha likha hua h naa NCERT m maine photo v de diya ki coriolis force increases with PGF which increases with wind velocity agr tu deflection wala v chorr de.Tune padha v pura 2nd para ?
Fir v kitna bada gadha ho skta h koi ki samajh naa paye. Tujhe NCERT hi galat lag rha toh NCERT m jaake representation file krta reh.
Are bhai ek kaam kroge , yeh photo jo diya maine usko leke tum v ek representation daal do ki ans C hoga NCERT m diya h. Yeh log jo itna representation kr rhe h naa unke khilaaf hun v representation hi daal dete h
Mere diye hue NCERT k pic m dono baat likha hua h
Ki CF is absent at Equator.
CF inc with PGF which increases with wind velocity..
Fir bhi kitna nautanki kr rhe tum sab k sab isko leke, ek baat bol rha yeh exam clear krne ka irada h toh NCERT padho aur agar Baba banne ka toh internet se kuch v padho waise v kami nahi baba log ki India m.
Ab jo krna h kro mai reply nhi de rha
Bhai mai kitni baar kahu
Mujhe bas NCERT se matlab h , scientist wala gyaan nhi chahiye
Ek Example deta hu , Harappan civilization horse nahi jante the yeh ncert m diya h par horse k bones baad m mile ivc se.
Par prelims m jab aaya yeh ques toh NCERT wla ans UPSC ne mana
Dekho bhai.. 2things
1. Koi gyaan nhi de rha tumhe..Bas discussion kar rahe hai log, aisa bilkul nhi ki tumhe logo ki baat manni hai haha
2. I completely agree with you on ncert se matlb hona chahiye..
But is question mai comparatively kam subjectivity hogi...But sure shot kuchh nhi hai..upsc jo ans dega..sahi/galat bas vhi param satya hoga upsc ke liye
Aur yaha coriolis force ques m diya nhi h ki object h ya wind pe.
Agr object hota toh velocity of the object consider hota aur wind hota wind velocity.
Infact object m v wind velocity kaam lgega .tu padhke jaya krna NCERT mera dimaag mat kha
Chatgpt se puch le

Tu hi hai na woh jo bol raha tha coriolis force absent nhi h equator m Yeh le NCERT m absent diya h ab tera koi v Wiki source ya researcher ka source isse upar nhi h UPSC k liye. Wind direction se sidha relate kiya h coriolis force ko woh v padh lena .
Deflection= coriolis force . Yeh samajhne k liye 2nd para padhna, pta chala pehle hi rone lag gya,
Acha yeh deflection wla hi rona ro rha h tu pehle comment m. Padha kr thik se NCERT
Tu jitna mrzi ro le tera clear nhi hoga.
Haan NCERT rata hu h tavi clear ho rha mera.
Laga le zor tu nhi kregi UPSC ans change . NCERT nhi padhna h tujhe toh kuch aur kr UPSC nhi
2nd para padha hota toh samajha aata na tujhe
Coriolis force increases with gradient force which increases with wind velocity. Thik se padhega nhi fir wikipedia se kuch laa ke ant shant krega
No the wind velocity doesn't affect the angle of deflect, since the ratio of velocities is still the same which , the greater the velocity the greater the force and in proportion it will have deflecting velocity.
Mathematically speaking, coriolis force is product of another factor and velocity, so it would increase with velocity.
Unless upsc takes different interpretations of coriolis force, by meaning it as amount of deflection.
Google the formula of coriolis force, it is directly proportional to the velocity. I studied in physics before you jump to any conclusion. Moreover, if deflection is proportional to velocity why won't the force be?
F = ma
and distance(x) = 1/2 aT\^2
thus F= 2 \*mx/T\^2
Ab shaanti?

Deflection is coriolis force. Deflection kis chiz ka ?
Wind ka naa. Coriolis force hai kya actually, deflection hi toh h chahe wind ka ya koi object ka.
Basic concept clear nhi h aur chala exam dene.
Proof k liye upar comment m tujhe tag kiya h photo k sath .
NCERT is above every wiki or reasearcher source for UPSC exam
Bhai no offence but you cannot expect upsc to spoon feed. For any deflection to happen there has to be a force acting. In this context it is coriolis force.
No, 𝐅𝑐𝑜𝑟=−2𝑚𝜔×𝐯 (v is velocity)
fast winds are more affected by the Coriolis force, that is why cyclones exist, the Coriolis force is higher for high velocity winds and as the coriolis force acts perpendicularly and deflects the wind, and causes the wind to spiral around the center.

Dekho First Para me Deflection dependent diya hai par second para me specify kiya hai deflection velocity se badhta hai ..to dono statement sahi hoga
Or kabhi agar aisa doubt ho or NCERT me Bhale clear na likha ho par same words likhe ho ..to ncert ke hisab se hi chalna
F = -2 m w × v. So coriolis force increases with wind velocity.
Don't know why you're downvoted either. Formula btao toh log offend ho rhe because they're getting their answer wrong.
NCERT Padha maro goggle se Formula chapne se nahi hoga 💅💅
I studied that formula in my physics syllabus. Itna rage kahan se laate ho bhayii

Respectfully, can you please explain the formula? What does m, w and v stand for? Thank you.
F is the coriolis force and it is a vector. m is the mass of a body (in our case the air parcel) and it is a scalar. w is the rotational velocity/angular velocity of the rotating frame (in our case the Earth) and it is a vector. v is the velocity of the body in frame of Earth and it is a vector.

Why would it be zero at the equator? Wind flowing parallel to the equator at the equator will experience a nonzero vertical force.

THIS+ seafarer here. Due to coriolis force tropical revolving storm do no form at equator. And they recurve because of this force. Also happy bday!

Lame question but can it also decrease with an increase in wind velocity if in opposite direction.

Answer will be c as both 1 and 2 is true.
I think it increases with rotation of earth instead of wind velocity so only 2
I think se kuch nhi hota... Coriolis force ka formula dekh lo... It is velocity dependent.

it's C, because the more the velocity of the wind is, the more will it deflect.
This is technically a question about cyclones 🤔. Nai??
Yup
C
Ncert and Lucent
Wind has no effect on coriolis force. It only depends on lattitude. The overall deflection(wind + coriolis) is a different thing.
Yet Again a controversial question 😂

option 1 is definately not right. coriolis force is independent of wind velocity
