JEE Main Physics question

Statement 1: Work done in the motion of a body over a closed loop is zero for every force in nature. Statement 2: Work done does not depend on the nature of force.

(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

The closed-loop work-done-is-zero property holds only for conservative forces (like gravitational or electrostatic forces), not for every force in nature (e.g. friction does non-zero work over a closed
