Is My Thinking Reasonable: A's Impact on Oscillator Motion

[hidemi]

Homework Statement

A sinusoidal force with a given amplitude is applied to an oscillator. At resonance the amplitude of the oscillation is limited by:
A. the damping force
B. the initial amplitude
C. the initial velocity
D. the force of gravity
E. none of the above

The answer is A

Relevant Equations

F = -kx

I just want to check if my thinking is reasonable. Since B,C and D are all dependent or fixed by the oscillator, A is the only factor to affect the amplitude of the motion at resonance or even throughout the entire process?

 

[Gordianus]

I think it would be better to know why the answer is A.

 

[Orodruin]

The damping force is also generally a property of the oscillator.

In order to deduce why A is the correct answer, you need to consider the actual physics of the oscillator.

Thank you all. I got it.
