Chapter 24, Problem 14P
Two charged particles of equal magnitude are located along the y axis equal distances above and below the x axis as shown in Figure P24.14. (a) Plot a graph of the electric potential at points along the x axis over the interval −3a < x < 3a. You should plot the potential in units of keQ/a. (b) Let the charge of the particle located at y = −a be negative. Plot the potential along the y axis over the interval −4a < y < 4a.
