An infinitely large layer of charge of uniform thickness t is placed normal to an existing uniform electric field. The charge on the sheet alters the electric field so that it still remains uniform on both the sides of the sheet and assumes values E1andE2 as shown in figure. The charge distribution in the layer is not uniform and depends only on the distance from its faces. Find the expressions for the force F per unit experienced by the charge layer.
