Electric Fields (Uniformly Charged Plates)

[QUOTE="Ian Baughman, post: 5491914, member: 554402"] [h2]Homework Statement [/h2] In the figure two large, thin metal plates are parallel and close to each other. On their inner faces, the plates have excess surface charge densities of opposite signs and magnitude 7.76 × 10-22 C/m2. What is the magnitude of the electric field at points [B](a)[/B] to the left of the plates, [B](b)[/B] to the right of them, and [B](c)[/B] between them?[ATTACH=full]188322[/ATTACH] [h2]Homework Equations[/h2] [/B] Gauss' Law [h2]The Attempt at a Solution[/h2] [/B] So I understand how to solve this problem and I am getting the correct solution but I was hoping for some clarification When using the pillbox method for gauss' law you consider two areas, the top and bottom part of the cylinder that is penetrating the plane. In parts a and b we still consider both areas but why wouldn't we just consider the area to the left or area to the right? Hopefully this makes sense! [/QUOTE]
