In the circuit below, the switch is initially open, and the initial voltage (at t= 0) at node V is2 volts. After ten seconds (at t = 10s) the switch closes. The switch remains closed for20 milliseconds, at which point (at t = 10.02s) it reopens. Calculate the voltage at node V(across the capacitor) after a total of 20 minutes has elapsed (t = 1200s).
