Two charged objects are sitting on the x-axis. The first object is located at the origin with a charge of +0.25 mC. The second object is located at (x, y) = (0, 5.0 cm) with a charge of - 0.25 mC. What is the energy needed to move both charges from an infinite distance away to the positions they are in now? If the electric potential an infinite distance away is set to be 0V, what is the electric potential at the point halfway among the two charges?
