Under the action of a constant voltage `U`, a capacitor of capacitance `C =10^(-11) F`

included in the circuit shown in Fig. 113 is charged to `q_(1) = 10^(-9) C`. The inductance of the coil, is `L = 10^(-5) H`, and the resistance of the resistor is `R = 100 Omega`.
Determine the amplitude `q_(0)` of steadystate oscillations of the charge on the capacitor at resonance if the amplitude of the external sinusoidal voltage is `U_(0) = U`.
