Which of the following statements regarding damping force of a damped oscillator is NOT correct?

Which of the following statements regarding damping force of a damped oscillator is NOT correct?
  1. Damping force depends on the nature of the surrunding medium.
  2. Damping force is generally proportional to the velucity of the body making oscillations.
  3. Damping force acts in the direction of the velocity of the budy.
  4. Ratio of the damping force and velocity of the body depends on the size and shape of the body.

Solution

Damping force always be consider in the opposite direction to the velocity.
