Q. If a body is executing simple harmonic motion then
A) At extreme positions, the total energy is zero
B) At equilibrium position, the total energy is in the form of potential energy
C) At equilibrium position, the total energy is in the form of kinetic energy
D) At extreme position, the total energy is infinite
Explanation
(c) At equilibrium position, potential energy of the body is zero. So, the total energy at equilibrium position is completely kinetic energy.
