Answer Key / Explanation : (c) -

(c)

Let same mass and same outer radii of solid sphere and hollow sphere are  and  respectively. The moment of inertia of solid sphere  about its diameter

                                                    ...(i)

Similarly, the moment of inertia of hollow sphere (spherical shell)  about its diameter

                                                   …(ii)

It is clear from Eqs. (i) and (ii), we get
