A rigid body not fixed in some way can have either pure translation or a combination of translation and rotation.
In rotation about a fixed axis, every particle of the rigid body moves in a circle which lies in a plane perpendicular to the axis and has its centre on the axis.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
B
(b) A rigid body fixed at one point or along a line can have only rotational motion. A rigid body not fixed in some way can have either pure translation or a combination of translation and rotation.

Motion of the rigid body is observed from an inertial frame of reference. Rigid body is rotating with nonuniform angular speed about a fixed vertical axis. If we consider a particle of the rigid body not lying on its axis of rotation then net force acting on this particle is

Motion of the rigid body is observed from an inertial frame of reference. Rigid body is rotating with constant angular speed about a fixed vertical axis. If we consider a particle of the rigid body not lying on its axis of rotation then net force acting on this particle is.
