Question details

Satisfied with her previous experiment in the vacuum chamber, Prof. Marcia Grail needs to store a great deal of energy in order to launch her next attempt at world domination. She decides to store this energy in a gigantic parallel plate capacitor, with the area of the plates fixed, and the distance between the plates minutely tunable. This capacitor is placed in the vacuum chamber from the previous, and the atmosphere removed. If the capacitance is 0.01 Farad, and is meant to store an energy of 20 GJ, then what voltage would need to be applied? How much charge does this correspond to?
