Among the four graphs shown in the figure there is only one graph for which average velocity over the time interval (0,T) can vanish for a suitably chosen `T`. Which one is it ?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
(b)
In the graph (b), for one value of displacement, there are two timings. As a result of it, for one time, the average velocity is positive and for one time is equal but negative. Due to it the average velocity for timings (equal to time period) can vanish.
