E Field in a shell(!) I have a shell with an inner radius 2m and an outer radius 3m and a cahrge q on the shell(distributed) , why is the E field at 1m is zero(charge enclosed is zero inside the sphere i can obtain it is zero but why doesn't the E field lines go into the shell)(this can be...

your first question; why doesn't -Q contribute to the E field, the anwer is simple E field is force per coulomb first find the force it is Q^2/4pi R^2 then divide it by Q, second you asked the parallel plate capacitor, when you are trying to find the E field of an infinite sheet of charge...
