The acceleration of a particle performing S.H.M. is 12 cm/`s^(2)` at a distance of 3 cm from the mean position. Its time period is _____ .

A

2 sec

B

4 sec

C

1.54 sec

D

3.14 sec

Text Solution

Verified by Experts

The correct Answer is:
D
In S.H.M `" " alpha = omega^(2)y`
`implies " " omega^(2) = (alpha)/(y) = (12)/(3) = 4 sec^(-2)`
`:. " "T= (2pi)/(omega)=(2pi)/(2) = pi= 3.14 sec`
