    A body is in pure rotation. The linear speed
    νof a particle, the distance r of the particle from the axis and the angular velocity
    ωof the body are related as
    ω=νr. Thus
    (a)
    ω=νr
    (b)
    ω∝r
    (c)
    ω=0
    (d)
    ωis independent of r.
    digAnsr:   d
    Ans : (d) `` \omega `` is independent of r
    In a pure rotation, angular velocity of all the particles remains same and does not depend on the position of the particle from the axis of rotation.
