Homework Help: physics

A spherical shell of uniform charge density σ has a circular hole cut out of it.What is the Electric Field at a radius just outside the sphere, directly over the center of the circular, cut-out hole? Type "sigma" for σ and "epsilon_o" for ϵo. HINT: the hole is small enough that you can treat it as flat, and the point at which you are calculating the field is so close to the hole that it can be approximated as an infiniate plane.
