Questions
The total energy of a particle executing SHM is 48 Joule. Then find its potential energy when its displacement is half of the amplitude.
detailed solution
Correct option is D
E = Total Energy =12 mω2 A2∴ 12 mω2 =E/ A2Now, U = Potential Energy 12 mω2 x2When x=A2, U=EA2 × A22=E4=484 J=12J.Talk to our academic expert!
