In a rigid body, the distances between pairs of particles:
AVary at random
BDo not change
CKeep growing
DKeep shrinking
Answer & Solution
Correct answer: B. Do not change
1. The shape of a rigid body never alters.
2. That means every particle keeps its place relative to the others.
3. So the distances between them do not change.
