Calculate the electric potential energy in a capacitor that stores 1.0 * 10 ^ - 10 of charge at 100.0v

Answerthe distance between the two ends of the galaxy is 150,000 light years;

Ke reqd to move from 0 to 50 will be proportional to 50x50 or 2500. this is equal to w.  to change vel from 50 to 150 you need energy prop to 22500 - 2500 = 20,000. this corresponds to 8w.  best answer is a) . work reqd is prop to velocity squared.
