A small mass executes linear `SHM` about `O` with amplitude a and period `T`. Its displacement from `O` at time `T//8` after passing through `O` is:

A

`(a)/(8)`

B

`(a)/(2sqrt2)`

C

`(a)/(2)`

D

`(a)/(sqrt2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`x=Asinomegat`
`x=Asin((2pi)/(T))xx(T)/(8)`
or `x=Asin((pi)/(4))=(A)/(sqrt2)`
