The radius of gyration of a ring of radius R about an axis through its centre and perpendicular to its plane is

Two rings have their moment of inertia in the ratio 2:1 and their diameters are in the ratio 2:1. The ratio of their masses will be:

The radius of gyration of uniform rod of length L and mass M about an axis passing through its centre and perpendicular to its length is

Moment of inertia of two spheres of equal radii are equal. One of the spheres is solid and has the mass 5 kg and the other is a hollow sphere. What is the mass of hollow sphere?

A solid cylinder of 200g and radius 10 cm has a moment of inertia (about its natural axis)

There are two circular iron discs A and B having masses in the ratio 1:2 and diameter in the ratio 2:1. The ratio of their moment of inertia is

The moment of inertia of two spheres of equal masses is equal. If one of the spheres is solid of radius  m and the other is a hollow sphere. What is the radius of the hollow sphere?

The moment of inertia of a body is independent of

The moment of inertia of a solid sphere about its diameter is .Find moment of inertia about its tangent.

A ring has greater moment of inertia than a circular disc of same mass and radius, about an axis passing through its centre of mass perpendicular to its plane, because
