An inductor and a resistor are connected in series to an ac source. The current in the circuit is 500 mA if the applied ac voltage is 8√2V at a frequency of

Hz and the current in the circuit is 400 mA if the same ac voltage at a frequency of

Hz is applied. The values of the inductance and resistance are respectively

60 mH, 71 Ω
√60 mH, 71 Ω
√60 mH, √71 Ω
60 mH, √71 Ω
