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
