The restoring force of SHM is maximum when particle:

Explanation

The restoring force of Simple Harmonic Motion (SHM) is maximum when the displacement of the particle is maximum. In SHM, the restoring force is given by Hooke's Law: F = -kx Where: F is the restoring force, k is the spring constant, and x is the displacement of the particle from its equilibrium position. The negative sign indicates that the restoring force acts in the opposite direction to the displacement. Now, let's consider the particle's displacement at different points in its motion. When the particle is at the maximum displacement (either positive or negative), the value of x is at its maximum. If we substitute the maximum displacement value into the equation, we get: F = -k * xmax Since the displacement is at its maximum, the magnitude of the restoring force is also at its maximum.
