9-1. Consider an infinite grounded conducting pipe with a square cross sectional area. Within the pipe is a uniform charge density r. Using the method of relaxation, and any computer software with which you are comfortable, determine the F(x,y). What grid size is needed to determine the correct potential of the center of the pipe to within 1%? (The correct value at the center of the pipe is F₀ = 0.0737 rL²/e₀)

9-2. Problem 2.29 in Jackson
