Q. In rotational motion of a rigid body, all particles move with
A) Same linear & angular velocity
B) Same linear and different angular velocity
C) With different linear velocities and same angular velocities
D) With different linear velocities and different angular velocities
Explanation
(c) As the body is rigid therefore angular velocity of all particles will be same $i.e.\ \omega =$ constant

From $v = r\omega,\ v \propto r$ (if $\omega =$ constant)
It means linear velocity of that particle will be more, whose distance from the centre is more, $i.e.\ v_{A} < v_{B} < v_{C}$ but $\omega_{A} = \omega_{B} = \omega_{C}$
