Question

In case of a forced vibration, the resonance wave becomes very sharp when the
A. applied periodic force is smaal
B. quality factor is small
C. damping force is small
D. restoring force is small

Answer 1

Correct Answer - C
In this case, sharp resonance will take place. But if it reduces by a small factor, then flat resonance will take place. The sharp and flat resonance will depend on damping present in the body executing resonant vibrations. Less the damping, greater will be sharpness.
