In forced oscillation of a particle the amplitude is maximum for a frequency ω1\omega_1 of the force, while the energy is maximum for a frequency ω2\omega_2 of the force, then

Options

  1. Aω1=ω2\omega_1=\omega_2
  2. Bω1>ω2\omega_1>\omega_2
  3. Cω1<ω2\omega_1 < \omega_2 when damping is small and ω1>ω2\omega_1>\omega_2 when damping is large
  4. Dω1<ω2\omega_1 < \omega_2

Correct answer

A. ω1=ω2\omega_1=\omega_2

Step-by-step solution

Both amplitude and energy get maximised when the frequency is equal to the natural frequency. This is the condition of resonance. \omega_1=\omega_2
