Question

Graph below shows variation of amplitude of forced oscillation with respect to frequency of driving force (natural frequency). Choose the correct statement(s). (A) Amplitude is maximum at ωd=ω. (B) Peak amplitude is maximum for curve a because for curve a damping is minimum. (C) Both (a) and (b) (D) None of the above

From the given figure, amplitude is maximum when (ωd/ω)=1, i.e. ωd=ω. Also the peak of amplitude is maximum for curve a which has least damping. With further increase in damping, amplitude decreases.

Amplitude is maximum at $ω_{d} = ω$ .

Peak amplitude is maximum for curve $a$ because for curve $a$ damping is minimum.

Both (a) and (b)

None of the above

From the given figure, amplitude is maximum when $\frac{ω _{d}}{ω} = 1$ , i.e. $ω_{d} = ω$ . Also the peak of amplitude is maximum for curve $a$ which has least damping. With further increase in damping, amplitude decreases.
