Under forced oscillation, the phase of the harmonic motion of the particle and phase of driving force
Under forced oscillation, the phase of the harmonic motion of the particle and phase of driving force
The correct option is D. Are different
Under forced oscillation, the phase of the harmonic motion of the particle and phase of driving force are different.
When a body oscillates by being affected by an external periodic force, it is called forced oscillation. Here, the amplitude of oscillation, experiences damping but remains constant due to the external energy supplied to the system. For example, when you push someone on a swing, you have to keep periodically pushing them so that the swing doesn’t reduce.
In forced oscillation, the frequency of the damped oscillation is equal to the frequency of the applied external force.
The forced oscillation does face the damping effect. But the supply of external force results in gaining the energy thereby maintaining constant amplitude.
