Four equal charges of 6nC are placed at the corners of an equilateral pyramid with each edge having a length of 0.30m.
A. How much energy, in joules, is stored in this configuration?
B. Assume that each of these individual charges has a mass of 5*10^-18kg. If one charge is released and allowed to be pushed away by the other charges (which are held in place), what will be the final velocity of the free charge? (Assume the potential energy is zero.)
