In a Simple Harmonic Motion - Physics

Short Note

In a simple harmonic motion
(a) the maximum potential energy equals the maximum kinetic energy
(b) the minimum potential energy equals the minimum kinetic energy
(c) the minimum potential energy equals the maximum kinetic energy
(d) the maximum potential energy equals the minimum kinetic energy

Solution

(a) the maximum potential energy equals the maximum kinetic energy
(b) the minimum potential energy equals the minimum kinetic energy

In SHM,
maximum kinetic energy  = \[\frac{1}{2}k A^2\]

maximum potential energy =\[\frac{1}{2}k A^2\]

The minimum value of both kinetic and potential energy is zero. 
Therefore, in a simple harmonic motion the maximum kinetic energy and maximum potential energy are equal. Also, the minimum kinetic energy and the minimum potential energy are equal.

  Is there an error in this question or solution?
