Having come experimentally to an interesting electrostatic effect, I have returned, aged 47, to my old books in physics. It turns out that my books delight in using Gauss theorem etc. in rather ideal geometrical surface charge distribution, but never gave me the tools to answer to this simple question.
Let x,y,z be a system of axes.
In the x,y plane, there is an infinite plate of some width w assumed to be small for the sake of simplicity, made of some dielectric material.
A charge q is placed at (x,y,z) = (1, 0, 0). What is the electrical field for x < 0, and in particular along the x axis.
Same question if the plate is made of some conductive material.
Make any assumption, simplification or approximation you want about all the unspecified parameters like the dielectric constant etc., a partial answer being better than no answer at all. thx.
