circuit consists of an inductor coil with

L=5.00\,\mathrm{mH}

and a

20.0\,\mu\mathrm{F}

capacitor. There is negligible resistance in the circuit. The circuit is driven by a voltage source with

v=V_0\cos\omega t

. If

V_0=5.00\,\mathrm{mV}

and the frequency is twice the resonance frequency, determine: (a) The maximum charge on the capacitor. (b) The maximum current in the circuit. (c) The phase relationship between the voltages across the inductor, the capacitor, and the source.
