Question
the objects mass is 59.3 kg and you initially put the boxes of protons and electrons 58 m apart. Now you want to take the two boxes and move them farther apart, to a new distance of 110 m apart. How much work (that is, energy) would you have to expend to pull the boxes that much farther apart, fighting against the electrostatic attraction between them?
