A graph is drawn between the displacement and time taken for the oscillations of a simple pendulum is 2s. The length of the penddulum is _______ m ( if g = 10 `s^(-2) and pi^(2) =10`)

Options

A. 2
B. 1
C. 0.5
D. 0.25

Answer

B

Explanation

The frequency of the bob, i.e, the number of oscillations completed in one second = `1//2 Hz= 0.5 Hz`
