A particle oscillates, according to the ...

A particle oscillates, according to the equation x = 5 cos `(pit//2)` m. Then the particle moves from equilibrium position to the position of maximum displacement in time of

A

1 s

B

2 s

C

`1//2` s

D

4 s

Text Solution

Verified by Experts

The correct Answer is:
A
`x=5cos.(pi)/(2)t`
Compare it with x = cos `omegat`
`therefore omega=(pi)/(2)`
`(2pi)/(T)=(pi)/(2)thereforeT=4`
`t=(T)/(4)`
`=(4)/(4)=1s`
