Field on the axis of a circular opening of a plane - corrected exercises Gauss theorem


Consider a uniformly charged surface plane which is practiced in an empty hole of radius R and fillers.
Determine the electrostatic field at a point M of the axis of the hole.
We note s the surface density loads.


In physics, the electric field is the vector field created by electrically charged particles. More precisely, charged particles modify the local properties of space, which is precisely what the notion of field means. If another charge is in this field, it will be affected by the electric force exerted at a distance by the particle: the electric field is in a way the "mediator" of this action at a distance.
