The potential energy of a harmonic oscillator of mass 2 kg in its mean positioin is 5J. If its total energy is 9J and its amplitude is 0.01m, its period will be

Text Solution

Verified by Experts

`1/2kA^(2)+(9-5)=4J`
`:.k=8/(A^(2))=8/((0.01)^(2))=8xx10^(4)N//m`
`T=2pisqrt(m/k)=2pisqrt(2/(8xx10^(4)))=(pi)/100s`
