Consider again the charged planes in Problem 62 (Fig. P17.62), but now assume the inner plane has a charge density of -10 µC/cm² and the outer planes have charge densities +10 µC/cm². Find the electric field at points A, B, C, and D.

Data From Problem 62

Consider three very large, parallel planes of charge that are equally spaced as shown in Figure P17.62. These planes are insulators, and each is charged uniformly with +10 µC on every square centimeter of area on the top surface of each plane. Use Gauss’s law to determine the field at points A, B, C, and D.
