Two very large parallel, insulating sheets are separated by 8 cm. (Only a small portion near the center of the sheets is shown.) Sheet A has a charge density σA. A coordinate system is chosen such that the sheets lie in the yz-plane, with sheet A at x = 0. A graph of the electric field as a function of x is shown at right below.
Find the charge σB (sign and magnitude) of sheet B in terms of charge density σA of sheet A.
