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: (a) 10 (b) 20 (c) 0 (d) 15

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.
