Electrostatics: Gauss Theorem

This lecture covers the applications of the Gauss theorem in electrostatics, focusing on the electric field produced by a point charge. It explains how the electric field is radial due to symmetry, and how the total flux is related to the charges inside a closed surface. The lecture also discusses the behavior of charges in conductors, emphasizing that excess charges are located on the surface. Furthermore, it explores the concept of the electric field inside a conductor's cavity, where the field is zero. Examples like the Faraday cage are used to illustrate these principles.
