In linear S.H.M., the restoring force on the particle is directly proportional to
Asquare of velocity (typical)
Bamplitude squared
Cdisplacement from mean position
Dtime elapsed
Answer & Solution
Correct answer: C. displacement from mean position
1. The defining equation of linear S.H.M. is F = −kx.
2. Here x is the displacement from the mean (equilibrium) position.
3. Hence the magnitude of the restoring force is proportional to displacement.
