A rigid body is the one in which
A rigid body is the one in which
Show Hint
Rigid body is an ideal concept — real bodies deform slightly under force.

- it can have only rotational motion
- it can have only translational motion
- the distances between all pairs of particles of the body do not change
- its shape can be deformed
- its centre of mass always lies inside the material of the body

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
A rigid body is an idealized object in which the distance between any two particles remains constant, regardless of external forces.
Step 1: Key property:
• No deformation occurs
• Shape and size remain fixed
Step 2: Analyze options:
• (A), (B): Body can have both motions → Incorrect
• (C): Definition of rigid body → Correct
• (D): Deformation allowed → Incorrect
• (E): Not always true → Incorrect Final Answer: Distances between particles remain constant.
