1)

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


A) Angular velocity

B) Angular momentum

C) Moment of inertia

D) Rotational kinetic energy

Answer:

Option B

Explanation:

Taking the same mass of sphere if the radius is increased then moment of inertia, angular velocity, and rotational kinetic energy will change but according to the law of conservation of momentum, angular momentum will not change.
