Question

Motion of a rigid body which takes place in such a way that all of its particles move in a circle about a fixed axis with common angular velocity. Type of motion of rigid body is

• A. Pure translational motion
• B. Pure rotational motion
• C. Combined translational and rotational motion
• D. None of these

Answer 1

The correct option is B Pure rotational motion

As we know,
In pure rotational motion, every particle of rigid body executes circular motion with common angular velocity and locus of centers of all circular motion is known as axis of rotation which remains fixed for pure rotation.
