A solid spherical ball and a hollow spherical
ball of two different materials of densities p,
and p, respectively have same outer radii and
same mass. What will be the ratio, the
moment of inertia (about an axis passing
through the centre) of the hollow sphere to
that of the solid sphere?

Explanation:
The solid sphere and the hollow sphere have the same mass and radius. Both are rotating at same speed. Here, M is the mass of solid sphere and R is the radius of solid sphere. Here, M is the mass of hollow sphere and R is the radius of hollow sphere.
