In the case of a simple pendulum, a graph is drawn between the displacement and time taken for its oscillations as shown in the figure. Then

Time period of the pendulum bob is ______ s.

A

3

B

4

C

2

D

`3^(1/2)`

Text Solution

Verified by Experts

The correct Answer is:
D
From the graph, it is clear that the bob is undergoing `3(1)/2` oscillations, i.e., for one oscillation it takes 6 seconds.
`therefore` In 21 seconds, it performs `21/6=3(1)/2` oscillations.
