Referring to Problem 84, calculatc and plot the electric potential on the circle centered at (0.50 m, 0). Give your results in terms of the angle ×, defined as follows: θ is the angle measured counterclockwise from a vertex at the center of the circle, with θ = 0 at point C.

Problem

A + 1.2-μC charge and a −1.2-μC charge are placed at (0.50 m, 0) and (−0.50 m, 0), respectively. (a) In Figure 20-29, at which of the points A, B, C, or D is the electric potential smallest in value? At which of these points does it have its greatest value? Explain. (b) Calculate the electric potential at points A, B, C, and D.
