A particle executes S.H.M. along x -axis. The force acting on it is given by (a) Acos (kx) (b) Ae-kx (c) Akx (d) -Akx

Answer: (d). In SHM the restoring force is F = -kx: proportional to x and directed towards the mean position. Only -Akx has this form. So the answer is (d) -Akx.

Periodic Motion & SHM Basics

A particle executes S.H.M. along $x$ -axis. The force acting on it is given by

Show answer and solution

Answer: (d)

In SHM the restoring force is $F = -kx$ : proportional to $x$ and directed towards the mean position.
Only $-Akx$ has this form.
So the answer is (d) $-Akx$ .
