    The axis of rotation of a purely rotating body
    (a) must pass through the centre of mass
    (b) may pass through the centre of mass
    (c) must pass through a particle of the body
    (d) may pass through a particle of the body.
    digAnsr:   b,d
    Ans : (b) may pass through the centre of mass
    (d) may pass through a particle of the body
