An electric field is set up between two parallel plates, each of area $2\mathrm{.}0m^2,$ by putting $1\mathrm{.}0C$ of charge on one plate and $-1\mathrm{.}0C$ of charge on the other. The plates are separated by $4\mathrm{.}0$ mm with their centers opposite each other, and the charges are distributed uniformly over the surface of the plates. What is the magnitude of the electric field between the plates at a distance of $1\mathrm{.}0$ mm from the positive plate, but not near the edges of the plates?
