How does NTA assume that students can solve such a question within one minute? :)

Same question come in AIEEE 2011 and then NEET 2016

[Sabanasabnam]

How can NEET examiner think that the student will solve this Q within 1 min as the teacher itself taking 5 min 😂

Sir yaha x ka power 3/2 hai es me chain rule समझ nahi aaya

[studywithme]

This que was also asked in jee mains 2011

[satyamkumarjha]

According to me, this answer is not practically correct, because if charge is leaking, so mass is variable, but here mass is assumed to be constant.
If I am wrong, please correct me

[dontforgetplease]

Even if I solve this question before exam and familiar with formula no way I can do it in 1minute lol..

[Escapeworld-]

Sir first we have taken the distance x then we took it x/2? I didn't get the point clear.

[kotamasterji]

Sir you considered that net force is zero then how speed is changing ?

[Guest]

It's que of aieee 2011 and asked in neet in 2016

[prakharraj]

X ^3/2 ko differentiate kar ne ke baad dx/dt kyu likhe

[RAHA]
