Consider the following the statements 1. The oscillation of a particle with fundamental frequency under the influence of restoring force is defined as forced oscillations 2. The oscillation of a body whose amplitude goes on decreasing with time is defined as damped oscillation. 3. The oscillation in which a body oscillates under the influence of an external periodic force is known as forced oscillation. Which of the following statements is/are correct? Correct Answer Both 2 and 3

CONCEPT:

  • Damped oscillation: The oscillation of a body whose amplitude goes on decreasing with time are defined as a damped oscillation.
  • Forced oscillation: The oscillation in which a body oscillates under the influence of an external periodic force is known as forced oscillation.
  • The external agent which exerts the periodic force is called the driver and the oscillating system under consideration is called the driver body.

EXPLANATION:

  • The oscillation of a particle with fundamental frequency under the influence of restoring force is defined as free oscillations. Therefore statement 1 is incorrect.
  • The oscillation of a body whose amplitude goes on decreasing with time is defined as a damped oscillation. Therefore statement 2 is correct.
  • The oscillation in which a body oscillates under the influence of an external periodic force is known as forced oscillation. Therefore statement 3 is incorrect.

Statement: Resonance is a special case of forced vibration in which the nature and frequency of vibration of the body are the same as the impressed frequency and the amplitude of forced vibration, is maximum. Reason: The amplitude of forced vibrations of a body increases with an increase in the frequency of the externally impressed periodic force.
