Chapter 21, Problem 21.37E
Two positive point charges q are placed on the .x-axis, one at x = a and one at .x = −a. (a) Find the magnitude and direction of the electric field at x = 0. (b) Derive an expression for the electric field at points on the x-axis. Use your result to graph the x-component of the electric field as a function of x, for values of x between −4a and +4a.
