The figure shows a simple RC circuit consisting of a 10.0-µF capacitor in series with a resistor.Initially,the switch is open as suggested in the figure.The capacitor has been charged so that the potential difference between its plates is 100.0 V.At t = 0 s,the switch is closed.The capacitor discharges exponentially so that 2.0 s after the switch is closed,the potential difference between the capacitor plates is 37 V.In other words,in 2.0 s the potential difference between the capacitor plates is reduced to 37 % of its original value.

-Calculate the electric potential energy stored in the capacitor before the switch is closed.
A)0.01 J
B)0.02 J
C)0.03 J
D)0.04 J
E)0.05 J
