Among the four graph shown in the figure...

Among the four graph shown in the figure there is only one graph for which average velocity over the time interval (O,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 graph (b) there are tgwo positions for one value of displacement. Hence for one time, the average velocity id positive and for another time it is negative.
Hence, there are opposite velocities in the interval 0 to T so, average velocity can vanish in (b). This can be seen in the figure given below

Here, `OA=BT` (same displacement) for two different points of time.
