hree parallel sheets of charge, large enough to be treated as infinite sheets, are perpendicular to the xx-axis. Sheet AA has surface charge density σAσA = +8.00 nC/m2nC/m2. Sheet BB is 4.00 cmcm to the right of sheet AA and has surface charge density σBσB = -4.00 nC/m2nC/m2. Sheet CC is 4.00 cmcm to the right of sheet BB, so is 8.00 cmcm to the right of sheet AA, and has surface charge density σCσC = +6.00 nC/m2nC/m2. What are the magnitude and direction of the resultant electric field at a point that is midway between sheets BB and CC, or 2.00 cmcm from each of these two sheets?
