  4. Assertion :A rigid body not fixed in some way can have either pure translation or a combination of translation and rotation. Reason: 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.

Q. Assertion :A rigid body not fixed in some way can have either pure translation or a combination of translation and rotation.
Reason : 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.

System of Particles and Rotational Motion

Solution:

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.
