Physics v1

Coulomb's law the force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. Gauss Theorem the electric flux through any closed surface is equal to the net charge enclosed by the surface divided by permittivity of vacuum. Drift velocity is defined as the average velocity with which free electrons in a conductor get drifted in a direction opposite to the direction of the applied electric field.
