Question:

In Figure a small circular hole of radius R = 1.80 cm has been cut in the middle of an infinite, flat, non-conducting surface that has uniform charge density σ = 4.50pC/m2. A z axis, with its origin at the holes center, is perpendicular to the surface. In unit-vector notation, what is the electric field at point P at z = 2.56 cm?
