A finite rod of length L has total charge q, distributed uniformly along its length. The rod lies on the x-axis and is centered at the origin. Thus one endpoint is located at (-L/2,0), and the other is located at (L/2,0). Define the electric potential to be zero at an infinite distance away from the rod. Throughout this problem, you may use the constant k in place of the expression 4 (Figure 1) What is VA, the electric potential at point A (see the figure), located a distance d above the midpoint of the rod on the y axis? Express your answer in terms of L, d, q, and k. View Available Hint(s) ... ?
