The moment of inertia of a solid disc rotating along its diameter is 2.5 times higher than the
moment of inertia of a ring rotating in similar way. The moment of inertia of a solid sphere which has same radius as the disc and rotating in similar way, is 
times higher than the moment of inertia of the given ring. Here,
