Sr. # Questions Answers Choice
1 Smaller the damping, the resonance will be more flat more sharp both of them none of them
2 Smaller the damping, greater will be the frequency wavelength amplitude none of them
3 The damping depends upon the amplitude sharpness both of them none of them
4 The resonance will be sharp, if the amplitude decreases rapidly at a frequency equal to the resonant frequency slight different from the resonant frequency greatly different from the resonant frequency any one of them
5 In the resonance condition, the amplitude of the oscillator becomes very large very small zero any one of them
6 Shock absorber of the car is an example of resonance forced oscillations interference damped oscillations
