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

A

2

B

1

C

0.5

D

0.25

Text Solution

Verified by Experts

The correct Answer is:
B
As the time period of oscillation is (T)=2s
` T= 2 pi sqrt(l/g)`
` T^(2) = 4pi^(2) l/g`
`l (gT^(2) ) / (4 pi^(2) ) = (10 xx 4) / ( 4xx 10) = 1 m `
