A body is executing `SHM` under the action of force whose maximum magnitude is `5sqrt(2)N`. The magnitude of force acting on the particle at the instant when its kintentic energy and potential are euqal is `10x`. Find `x`. (Assume potenital energy to be zero at mean position)

Answer

5

Explanation

`F_(max) = momega^(2)A = 50sqrt(2)`
`KE = PE` at `X = (A)/(sqrt(2))`
`F = (momega^(2)A)/(sqrt(2)) = 50`
