A rigid body is rotating with angular velocity ' $\omega$ ' about an axis of rotation. Let $v$ ' be the linear velocity of particle which is at perpendicular distance ' $r$ ' from the axis of rotation. Then the relation $v=r \omega$ ' implies that

$\omega$ does not depend on $r$

$\omega \propto \frac{1}{r}$

$\omega \propto r$

$\omega=0$
