A 1 B ● 2 3 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 σ. The charge density on plate 2 is 3 o. The charge density on plate 3 is 0 σ. The charge density on plate 4 is -1 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 D? (in units of σ/ε0) 169.49 0/80 Remember that the electric field for each plate is E = 0/280. You must use this equation to find the magnitude of the electric field produced by each plate. You must then determine the direction of electric field produced by each plate. Remember that the field points towards the negative charge and away from the positive charge. Submit Answer Incorrect. Tries 1/2 Previous Tries
