Angular momentum of the particle rotatin...

Angular momentum of the particle rotating with a central force is constant due to

A

constant linear momentum

B

zero torque

C

constant torque

D

constant force

Text Solution

Verified by Experts

The correct Answer is:
B

Central forces pass through axis of rotation, so torque is zero. If no external torque is acting on a particle, the angular momentum of the particle is constant
