JEE Main Physics question

Statement 1: The angular momentum under a central force is constant. Statement 2: Inverse square law of force is conservative.

(A)Assertion is True, Reason is True; Reason is the correct explanation for Assertion
(B)Assertion is True, Reason is True; Reason is NOT the correct explanation for AssertionCorrect
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is True

Answer: (B)

Solution

A central force produces zero torque about the force centre (since and is along ), so angular momentum about that centre is conserved — Statement 1 is true. An inverse-square-law force is indeed conservative —
