Two infinite sheets having charge densities σ1 and σ2 are placed in two perpendicular planes whose two-dimensional view is shown in figure. The charges are distributed uniformly on the sheets in electrostatic equilibrium condition. Four points are marked I, II, III and IV. The electric field intensities at these points are E→1 , E→2, E→3 , and E→4, respectively. The correct expression for the electric field intensities is

A large charged metal sheet is placed in a uniform electric field, perpendicular to the electric field lines. After placing the sheet into the field, the electric field on the left side of the sheet is E1 = 5 × 10^5 V/m and on the right it is E2 = 3 × 10^5 V/m. The sheet experiences a net electric force of 0.08 N. Find the area of one face of the sheet. Assume the external field to remain constant after introducing the large sheet. Use (1/4πε0) = 9 × 10^9 N m^2 C^−2
