JEE Main Physics question

Statement 1: A light body and a heavy body have the same momentum. Then they also have the same kinetic energy. Statement 2: Kinetic energy does not depend on the mass of the body.

(A)Assertion is True, Reason is True; Reason is correct explanation for Assertion
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is TrueCorrect

Answer: (D)

Solution

Since E = p²/2m, for equal momentum, E ∝ 1/m — the lighter body actually has more kinetic energy, not the same, so Statement 1 is
