Problem

In a series L-C-R circuit, C=10−11C = 10^{-11} Farad, L=10−5L = 10^{-5} Henry and R=100R = 100 Ohm, when a constant D.C. voltage EE is applied to the circuit, the capacitor acquires a charge 10−910^{-9} C. The D.C. source is replaced by a sinusoidal voltage source in which the peak voltage E0E_0 is equal to the constant D.C. voltage EE . At resonance the peak value of the charge acquired by the capacitor will be : a. 10−1510^{-15} C b. 10−610^{-6} C c. 10−1010^{-10} C d. 10−810^{-8} C
