The angular momentum of a moving body remains constant if

A

Assertion and Reason are true and Reason is a correct explanation for Assertion

B

Assertion and Reason are true and Reason is not a correct explanation for Assertion.

C

Assertion is true and Reason is false.

D

Assertion is false and Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
Since the centripetal force is radial the torque due to this force is zero about the centre. Hence angular momentum is conserved only at the centre of the circle.
