Question

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

Answer 1

l think d option different

Answer 2

Answer:

The correct answer is option c) with different linear velocities and the same angular velocities.

Explanation:

In the rotational motion of the rigid body, all the particles cover the exact angular displacement in a certain interval. So, the angular velocities of all the particles will be exact.

But the linear velocity exists also dependent on the distance of particles from the axis of rotation. So, linear velocities will be different for all particles as the distances are various for all particles.

The correct answer is option c) with different linear velocities and the same angular velocities.
