Question

In rotational motion of a rigid body , all particle move with
a) same linear and angular velocity.

Answer 1

Explanation:

In rotational motion the angular velocity of all the constituent particle is the same . Because all particles will describe equal angles in equal interval of time . The relative displacement between is zero in case of rigid body .

If angular velocity is denoted by ω

The linear velocity v = r ω

here r is the distance of particle of the body from the axis of rotation , which is different for different particles .

Hence v is not the same for all particles .

Answer 2

Answer:

same linear and angular velocity
