In forced oscillation of a particle, the amplitude is maximum for a frequency ω1 of the force, while the energy is maximum for a frequency ω2 of the force. Then
A.
ω1=ω2
B.
ω1 is lessed than ω2
C.
ω1 is lesser than ω2, when damping is small and ω1 is greater than ω2, when damping is large
D.
ω1 is lesser than ω2
Answer: Option A
Explanation:
Only in case of resonance, both the amplitude and energy of oscillation are maximum. Hence, ω1=ω2.
