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?
Options
(a) moment of inertia
(b) angular momentum
(c) angular velocity
(d) rotational kinetic energy
Correct Answer:
angular momentum
Explanation:
Talking the same mass of sphere, if radius is increased, then moment of inertia, rotational kinetic energy and angular velocity will change but according to law of conservation of momentum, angular momentum will not change.
