Potential of Point-Charges: Three point charges are placed at the following points in a horizontal x-y plane: +4.0 ?C is at (0.00 m, 0.50 m), + 1.0 ?C is at 0.20 m, 0.00 m), and -5.0 × ?C is at (0.20 m, 0.50 m). Calculate the electrical potential (relative to infinity) at the origin due to these three point charges. (k = 1/4??0 = 9.0 × 109 N ? m2/C2)
