Charge on a Capacitor in an RC Circuit

EANDM-BJQ@GW

In the RC circuit below the capacitor is initially uncharged. At time $t = 0 \:\text s$ the switch is closed and the capacitor begins to charge. The circuit parameters are: $\Delta V = 10.0 \:\text V$, $R = 1.00 \:\text k \Omega$, $C= 20.0 \: \mu \text F$.
