Question
A periodic driving force of frequency ƒ acts on a system which undergoes forced oscillations of amplitude A. The graph below shows the variation with ƒ of A. The maximum amplitude A0 of the oscillations occurs at frequency ƒ0.
The damping of the system is now increased.
Which describes the change in ƒ0 and the change in A0?
