In the previous question, the amplitude of the oscillation is

A

`10 sqrt(2) cm`

B

`15 sqrt(2) cm`

C

`15 cm`

D

`20 cm`

Text Solution

Verified by Experts

The correct Answer is:
C
`KE_(max) = (1)/(2) kA^(2)`
`A = sqrt((2(KE_(max)))/(k)) = sqrt((2 xx (2.25))/(200)) = sqrt((9)/(400)) = (3)/(20) m = 15cm`
