The maximum restoring force of a body executing SHM is `alpha` and total energy is `beta` obtain it’s the amplitude in terms of `beta" and "alpha`.

Explanation

Maximum restoring force `F= kA`
`therefore alpha = kA`
Total energy `E= (1)/(2) kA^(2)`
`therefore beta = (1)/(2) kA^(2)`
`therefore (beta)/(alpha)= (A)/(2)`
`therefore A= (2beta)/(alpha)`.
