Question

Which of the following is/are correct about a rigid body? (i) Inter-particle distances are independent of the forces of constraints; (ii) Inter-particle distances is zero; (iii) Inter-particle distances are fixed by the forces of constraints
Options
A I only
B I & II
C I & III
D III only
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

In a rigid body, the distances between particles are fixed (constant) by the forces of constraints. They are not independent of forces, and they are not zero.

Hint

Rigid body means fixed shape, so fixed inter-particle distances.
