Question

The particle executing simple harmonic motion has a kinetic energy K0 cos^2 ωt. The maximum values of the potential energy and the total energy are respectively ___________

(a) Kc/2 and K0

(b) K0 and K0

(c) K0 and 2K0

(d) 0 and 2K0

Answer 1

The correct option is (b) K0 and K0

For explanation: When kinetic energy is maximum, potential energy is zero and vice-versa. But

Kinetic energy+ Potential energy = Total energy

Maximum potential energy = Maximum kinetic energy = Total energy = K0.
