A) \[{{\omega }_{1}}={{\omega }_{2}}\]
B) \[{{\omega }_{1}}>{{\omega }_{2}}\]
C) \[{{\omega }_{1}}<{{\omega }_{2}}\]when damping is small and\[{{\omega }_{1}}>{{\omega }_{2}}\] when damping is large
D) \[{{\omega }_{1}}<{{\omega }_{2}}\]
Correct Answer: A
Solution :
[a] |
For amplitude of oscillation and energy to be maximum, frequency of force must be equal to the initial frequency and this is only possible in case of resonance. |
In resonance state, |
