Multiple Choice

For the circuit shown in the figure, $C = 12 \mu \mathrm { F }$ and $R = 8.5 \mathrm { M } \Omega$ . Initially the switch $\mathrm { S }$ is open with the capacitor charged to a voltage of $80 \mathrm {~V}$ . The switch is then closed at time $t = 0.00 \mathrm {~s}$ . What is the charge on the capacitor, when the current in the circuit is $3.3 \mu \mathrm { A }$ ?

A) $620 \mu \mathrm { C }$
B) $340 \mu \mathrm { C }$
C) $480 \mu \mathrm { C }$
D) $700 \mu \mathrm { C }$
Е) $350 \mu \mathrm { C }$
