ACT: Parallel charged planes II
{"Image DocumentName": "ACT: Parallel charged planes II", "Image ImageDescription": "An uncharged metal slab is inserted between the two planes as shown below. Charge densities \u03c3L and \u03c3R appear on the sides of the slab. Compare the electric field at point P before and after the slab is introduced. \u03c3L + \u03c3R = 0. and distance from. the plane does not matter!
