The damping force on an oscillator is directly proportional to the velocity. The units of the constant of proportionality are
- $kg\,ms^{-1}$
- $kg\,ms^{-2}$
- $kg\,s^{-1}$
- $kg\,s$
The Correct Option is C
Solution and Explanation
$K =\frac{ F }{ v }$
Unit of $K =\frac{ kg ms ^{-2}}{ ms ^{-1}}= kg s ^{-1}$

Concepts Used:
Energy In Simple Harmonic Motion
We can note there involves a continuous interchange of potential and kinetic energy in a simple harmonic motion. The system that performs simple harmonic motion is called the harmonic oscillator.
Case 1: When the potential energy is zero, and the kinetic energy is a maximum at the equilibrium point where maximum displacement takes place.
Case 2: When the potential energy is maximum, and the kinetic energy is zero, at a maximum displacement point from the equilibrium point.
Case 3: The motion of the oscillating body has different values of potential and kinetic energy at other points.
