A series LCR circuit containing 5.0 H inductor, 80 µF capacitor and 40 Ω resistor is connected to 230 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:

(1) 42 rad/s and 58 rad/s

(2) 25 rad/s and 75 rad/s

(3) 50 rad/s and 25 rad/s

(4) 46 rad/s and 54 rad/s
