    Solution:

    The given statement is true.
    Concept: Here we have to derive the expression for kinetic energy by the formula of kinetic energy .
    The energy which a body possesses by virtue of being in motion is known as kinetic energy.
    As per the formula of rolling kinetic energy,
    But
    Therefore substituting the value of w in above equation
    Total Rolling Hence, Total Rolling Kinetic Energy of rolling rigid body is for solid sphere I,
    Solid sphere Total Rolling kinetic energy
    Total Rolling kinetic energy  Therefore, Total Rolling kinetic energy  Hence, the given statement is true.
