If the displacement of a body is zero is the distance covered by it necessarily zero ? Explain with suitable illustration.

A

Must be zero

B

May or may not be zero

C

Cannot be zero

D

Depends upon the particle

Text Solution

Verified by Experts

The correct Answer is:
B
If the dieplacement is zero, the distance moved may or may not be zero. For example, if a partcicle returns to its initial position after moving through a distance, desplacemen will be zero but distance coverd will not be zero.
