Question 188 of 194

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

Show answer and solution

Answer: (A) ω1=ω2\omega_1=\omega_2

Both amplitude and energy get maximised when the frequency is equal to the natural frequency. This is the condition of resonance.
ω1=ω2\omega_1=\omega_2
