In forced oscillation of a particle the amplitude is maximum for a frequency `omega_(2)` of the force while the energy is maximum for a frequecyomega_(2) of the force, then .A. (a) `omega_(1)ltomega_(2) when damping is small and `omega_(1)gtomega_(2)` when damping.B. (b) `omega_(1)gtomega_(2)`C. (c ) `omega_(1)=omega_(2)`D. (d) omega_(1)ltomwga_(2). |

Answer» Correct Answer - C (c )The maximum of amplitude and energy is obtained when the frequecy is equal to the natural freqency (resonance condition) :. Omega_(1)=omega_(2)`. |
