SWITCHING PROBLEMS OF CAPACITOR

The main problem with switching over to CNG is the difficultyof

The circuit consists of two resistors (of resistance R_(1) = 20 Omega and R_(2) = 10 Omega ), a capacitor (of capacitance C =10 muF ) and two ideal cells. In the circuit shown the capacitor is in steady state and the switch S is open The charge on capacitor in steady state with switch S closed.

The left most capacitor is uncharged. The other tow capacitors carry charges q_1 = 8muC and q_2 = 10muC . Now switch S is closed. Find the final charge on left most capacitor.

Two capacitors of equal capacitance ( C_1 = C_2 ) are shown in the figure. Initially, while the switch S is open, one of the capacitors is uncharged and the other carries charge Q0. The energy stored in the charged capacitor is U0. Sometimes after the switch is colsed, the capacitors C_1 and C_2 carry charges Q_1 and Q_2, respectively, the voltages across the capacitors are V_1 and V_2 , and the energies stored in the capacitors are U_1 and U_2 . Which of the following statements is INCORRECT ?
