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

Options

  1. ADamping force depends on the nature of the surrunding medium.
  2. BDamping force is generally proportional to the velucity of the body making oscillations.
  3. CDamping force acts in the direction of the velocity of the budy.
  4. DRatio of the damping force and velocity of the body depends on the size and shape of the body.

Correct answer

C. Damping force acts in the direction of the velocity of the budy.

Step-by-step solution

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