The capacitor `C_1` in the figure shown initially carries a charge `q_0`. When the switches `S_1` and `S_2` are closed,capacitor `C_1` is connected in series to a resistor `R` and a second capacitor `C_2` which is initially uncharged.
The flown through wires as a function of time is
where `C=(C_1C_2)/(C_1+C_2)`
A. `q_0e^(-t/(RC))+C/C_2q_0`
B. `(q_0C)/C_1x[1-e^(-t/(RC))]`
C. `q_0C/C_1e^(-t/(CR))`
D. `q_0e^(-t/(RC))`
