The oscillation of a body on a smooth horizental surface is respresented by the equation
`X = A cos (omegat)`
where one of the following graph shown correctly the variation a with `t`?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
(c)n`a=-omega^(2)x=-omega^(2)A"cos"omegat`
`therefore` a-t graph is -`"cos"omegat` graph
