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

A

Rotational kinetic energy

B

Moment of inertia

C

Angular velocity

D

Angular momentum

Text Solution

Verified by Experts

The correct Answer is:
D
`tau_(ex)=0`
So, `(dL)/(dt)=0`
i.e., L=constant
So angular momentum remains constant .
