A solid sphere is rotating in free space. If the radius of the sphere is increased keeping mass same which one of the following will not be affected ?

A

angular momentum

B

angular velocity

C

rotational kinetic energy

D

moment of inertia

Text Solution

Verified by Experts

The correct Answer is:
A

(a) As no external torque is acting on the sphere hence angular momentum of the sphere will be constant.
