A solid sphere is rotating in free space, Mechanical Engineering

Assignment Help:

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?

Solution) In free space, neither acceleration due to gravity for external torque act on the rotating solid sphere.Thus, taking the similar 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.
