Question

In rotational motion of a rigid body, all particles move
with
(a) same linear velocity and same angular velocity
(b) same linear velocity and different angular velocity
(c) different linear velocities and same angular velocities
(d) different linear velocities and different angular velocities​

Answer 1

In rotational motion of a rigid body, all particles move with (b) same linear velocity and different angular velocity.



How?
Nice question.

Consider the diagram,

The ball moves with a linear velocity v.
Now all the particles of the ball will be dispaced by same amount as the same particle next to them since they are binded by artifical / natural forces.

Now, there are particles as different distances from the center of the ball and since angular displacement = l/r. The greater the distance will be the smaller the displacement for that specific particle will be.


NOTE: Here l = distance changed and r = radius from the center of the ball.
