Vedclass · Answer

(B) Resonance is a phenomenon where the amplitude of oscillations increases significantly when the frequency of an externally applied periodic force matches the natural frequency of the system.In a forced oscillation system,the sharpness of the resonance curve is determined by the damping present in the system.The sharpness of the resonance is inversely proportional to the damping coefficient.Therefore,when the dampening force is small,the energy loss per cycle is minimal,leading to a very sharp and high-amplitude resonance peak.Thus,the correct option is $B$.

In case of a forced vibration,the resonance wave becomes very sharp when the:
