Ques in pic.
Ans: B
Why isnt A?
Statement 1: Escape velocity is independent of the angle of projection.
and
Statement 2: Escape velocity for vertical projection from the surface of Earth is
(A) Statement-1 is True, Statement-2 is True; Statement-2 is a correct explanation for Statement-1.
(B) Statement-1 is True, Statement-2 is True; Statement-2 is not a correct explanation for Statement-1.
(C) Statement-1 is True, Statement-2 is False.
(D) Statement-1 is False, Statement-2 is True.
Dear Student,
Look here you can see that statement 1 talks about the angle of projection and statement 2 talks about the escape velocity of the vertical projection of any projectile. Now to deduce this velocity we can see that vertical angle is 900 thus we don't need to use the angle related term. So here the statement 2 is not the correct explanation of statement 1. If we need to explain the statement 1 then we should have to approach through the derivation of escape velocity where we can assume that it is independent of angle of projection.
This is the reason that option B is correct.
Hope this helps you.
Regards
