d. 202N
2.Consider a circuit where a voltage supply potential difference V0 is connected to three capacitors. Suppose that capacitors C2 and C3 are connected in parallel, and the combination of C2 and C3 are connected in series with capacitor C1 and the voltage supply potential difference V0. IF C1=25uF, C2=20uF, C3=10uF, and the potential differenceV0=21V, determine the energy stored by C2.
a.0.72mJ
b.0.91mJ
c.0.32mJ
d.0.40mJ
