A teaching assistant builds a parallel-plate capacitor with adjustable spacing between the plates. When the plates are at their initial separation, the capacitance is 5.00 µF. (a) At this capacitance, the capacitor is connected to a 12.00 V battery. After fully charging, how much energy (in µJ) is stored in the capacitor? µJ (b) The battery is then disconnected. Without discharging the capacitor, the teaching assistant then doubles the separation between the plates. At this point, how much energy (in µJ) is stored in the capacitor? µJ (c) Without changing this new separation between the plates, the capacitor is discharged, and then reconnected to the 12.00 V battery. Now, after fully charging, how much energy (in µJ) is stored in the capacitor? µJ
