If a body starts its motion from point A to B and comes back to the same point after a certain time interval, the displacement is:
- 10
- 20
- 0
- 15
Answer
0
Reason — If a body starts its motion from point A to B and comes back to the same point after a certain time interval, the displacement is 0. For example: In a circular motion, the body comes back to the starting point after completing the circle, then displacement is zero but distance covered is not zero.
