Question

A linear harmonic oscillator has a total energy of 160 J. Its
(a) maximum potential energy is 100 J
(b) maximum kinetic energy is 160 J
(c) minimum potential energy is 100 J
(d) maximum kinetic energy is 100 J

Answer 1

For a simple harmonic oscillator total energy = maximum potential energy = maximum kinetic energy.
Therefore here only option  (B) is correct.
