  • question_answer 20)
    The oxygen molecule has a mass  and a moment of inertia of about an axis through its centre perpendicular to the line joining the two atoms. Suppose the mean speed of such a molecule in a gas is 500 m/ s and that its kinetic energy of rotation is two thirds of its kinetic energy of translation. Find the average angular velocity of the molecule.  

    Answer:

    Rotational  Translational K.E. or              or              .
