. A series LCR circuit containing \(5.0 \mathrm{H}\) inductor, \(80 \mu \mathrm{F}\) capacitor and \(40 \Omega\) resistor is connected to \(230 \mathrm{~V}\) variable frequency ac source. The angular frequencies of the source at which power transferred to the circuit is half the power at the resonant angular frequency are likely to be:
A \(25 \mathrm{rad} / \mathrm{s}\) and \(75 \mathrm{rad} / \mathrm{s}\)
B \(50 \mathrm{rad} / \mathrm{s}\) and \(25 \mathrm{rad} / \mathrm{s}\)
(c) \(46 \mathrm{rad} / \mathrm{s}\) and \(54 \mathrm{rad} / \mathrm{s}\)
D \(42 \mathrm{rad} / \mathrm{s}\) and \(58 \mathrm{rad} / \mathrm{s}\)
