    None of these forces contribute for these vibrations

    Explanation:

    The atoms or molecules of the solid substance vibrate at zero degree absolute even , due to kinetic energy of the constituent atoms or molecules .

    According to Kelvin , the kinetic energy of these particles should become zero at absolute zero .

    But it is found by actual calculations that the kinetic energy of constituent atoms or molecules does not become zero .

    Thus all the above forces are not considered as the main cause of these vibration .
