JEE MAIN - Physics (2004 - No. 48)
A solid sphere is rotating in free space. If the radius of the sphere is increased keeping mass same which on of the following will not be affected ?
Angular velocity
Angular momentum
Moment of inertia
Rotational kinetic energy
설명
Solid sphere is rotating in free space that means no external torque is operating on the sphere.
Angular momentum will remain the same since external torque is zero.
Angular momentum will remain the same since external torque is zero.
