Sticky Note
When is the restoring force minimum in simple harmonic motion (SHM), given F = -kx?
  1. At equilibrium (mid) position
  2. At half amplitude
  3. Always constant
  4. None of these
Explanation

In simple harmonic motion (SHM), the restoring force is given by:

F = -kx

Where:  

- F is the restoring force  

- k is the spring constant  

- x is the displacement from the equilibrium position  

The restoring force is minimum when displacement x = 0, i.e., at the equilibrium position.
