A hollow sphere of radius R is suspended from a thin rod. If the sphere is twisted by a small angle about the wire axis and released, simple harmonic oscillation (SHM) will ensure with a period of tr Now. if the hollow sphere is replaced by a solid sphereof radius and mass equal to that of hollow sphere, the SHM will have a period τ2. The ratio of time periods (τ1∕τ2) is
