Three point charges initially are infinitely far apart.
Chapter 19, Problem 19.111(choose chapter or problem)
Three point charges initially are infinitely far apart. Then, as Figure 19.10 shows, they are brought together and placed at the corners of an equilateral triangle. Each side of the triangle has a length of 0.50 m. Determine the electric potential energy of the triangular group. In other words, determine the amount by which the electric potential energy of the group differs from that of the three charges in their initial, infinitely separated, locations
