i. Suppose 8.9x10^-19 J of work is done to bring the nucleus of an atom from some infinite distance away to a particular location near a fixed positive charge. What would the electric potential energy of the nucleus be? ii. The nucleus is released an returns to the very far original position. Considering the kinetic energy of the nucleus and a mass of 6.6x10^-27 kg, which is closest to the velocity of the nucleus
