Question

In a simple harmonic motion, when the displacement from the equilibrium position is at its maximum,
a. The kinetic energy is at its maximum.
b. The magnitude of the net force is at its maximum.
c. The total mechanic energy is at its maximum.
d. The speed is at its maximum.
e.The potential energy is at its minimum.

Answer 1

Answer:

option B

Explanation:

The correct answer is option B

When the displacement in the harmonic motion is maximum then kinetic energy at the maximum point is minimum and the potential energy is maximum at that point.  

So, when the displacement is maximum, spring force magnitude is also maximum because the force is proportional to the displacement and also the magnitude of the acceleration is maximum so, the net force is also maximum.
