1 4 A В C D E The figure above shows four very thin parallel planes of charge with equal separation between them. The charge density on plate 1 is 0 o. The charge density on plate 2 is 2 o. The charge density on plate 3 is 1 o. The charge density on plate 4 is 5 o. Your answers for the electric field must include the correct sign. We choose positive electric field along the positive x-direction. What is the Electric Field at point B? (in units of o/ɛo)
