When a particle oscillates in simple harmonic motion, both in potential energy and kinetic energy vary sinusoidally with time. If `v` be the frequency of the motion of the particle, the frequency associated with the kinetic energy is `:`A. `4v`B. `2v`C. `v` is highest when the spring comes back to natural positionD. `(v)/(2)` |
