In the given circuit the capacitor (C) may be charged through resistance R by a battery V by closing switch `(S_1)`. Also when `(S_1)` is opend and `(S_2)` is closed the capacitor is connected in series with inductor (L). Given taht the total charge stored in the LC circuit is `(Q_0)`. for `Tge0, the charge on the capacitor isA. the charge on the capacitor is `Q=Q_(0) cos""((pi)/(2)+(t)/(sqrt(LC)))`B. the charge on the capacitor is `Q=Q_(0) cos""((pi)/(2)-(t)/(sqrt(LC)))`C. the charge on the capacitor is `Q= -LC(d^(2)Q)/(dt^(2))`D. the charge on the capacitor is `Q= -(1)/(sqrt(LC))(D^(2)Q)/(dt^(2))` |
