The particle executing simple harmonic motion has a kinetic energy K₀ cos² ωt. The maximum values of the potential energy and the total energy are respectively

1. K₀/2 and K₀
2. K₀ and 2K₀
3. K₀ and K₀
4. 0 and 2K₀

Correct answer: K₀ and K₀

Solution

In simple harmonic motion, the total energy is constant and equals the maximum kinetic energy, which is K₀. The maximum potential energy is also equal to the total energy, which is K₀.
