Assertion: A solid sphere and a hollow sphere are rolling on ground with same total kinetic energies. if translational kinetic energy of solid sphere is K, then translational kinetic energy of follow sphere should be greater than K. Reason: In case of hollow sphere rotational kinetic energy is less than its translational kinetic energy.

The mean rotational kinetic energy of a diatomic molecule at temperature T is :
