MCQ
Resonance is an example of
  • A
    Tuning fork
  • Forced vibration
  • C
    Free vibration
  • D
    Damped vibration

Answer

Correct option: B.
Forced vibration
b
(b)

Resonance can occur only if external force is applied at same frequency as that of natural frequency, hence it is forced vibration. Option B is correct.
