The two source charges (−Q at y = 0 and +9Q at y = d) remain fixed in place for the rest of this problem. Use the expression for V (y) given on the first page of this problem, which gives the potential due to these two charges only. (10d) (3 points) Calculate V at y1 = 2d and y2 = 3d. Show your work below, then record your answers. Solution: V (2d) = − kQ 2d + 9kQ 2d − d = − kQ 2d + 9kQ d = + 17kQ 2d = +7.6 × 105 V V (3d) = − kQ 3d + 9kQ 3d − d = − kQ ...
