A large sheet of charge has a uniform charge density of 10 μC/m2 . What is the electric field due to this charge at a point just above the surface of the sheet?

very long and thin insulating rod has a charge of +Q uniformly distributed along its length. The rod has a length L. Use Gauss’s lawto determine the electric field near the middle of the rod a short distance, d, from the axis of the rod.

1 2 3 A В E The figure above shows four very thin parallel planes of charge with equal separation between them. The charge density on plate 1 is 2 nC/m2. The charge density on plate 2 is -5 nC/m2. The charge density on plate 3 is 4 nC/m2. The charge density on plate 4 is 3 nC/m2. 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 N/C) N/C Submit Answer Tries 0/2

Two very large parallel sheets are 5.00 cm apart. Sheet A carries a uniform surface charge density of -7.80 µC/m², and sheet B, which is to the right of A, carries a uniform charge density of -13.6 C/m Assume that the sheets are large enough to be treated as infinite.
