(A): The size and shape of the rigid body remains unaffected under the effect of extemal forces.
(R): The distance between two particles remains constant in a rigid body.

View answer and explanation

Correct option: A

Both (A) and (R) are true and (R) is the correct explanation of (A)

Option A is correct because the definition of a rigid body implies that its size and shape remain unchanged under external forces, and this is because the distance between any two particles within the body remains constant.
