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

A

Angular velocity

B

Moment of inertia

C

Angular momentum

D

Rotational kinetic energy

Text Solution

Verified by Experts

The correct Answer is:
C
The angular momentum of the sphere remains constant because no external torque is acting on the sphere. `omega, I` and rotational K.E. are affected.
