Name this law that states that the permittivity constant times the surface integral of the electric field is equal to the enclosed charge.
This law is used to justify Earnshaw's Theorem because it can be used to show that the divergence of force fields is zero. It is easy to use it to find the strength of an electric field created by an infinite line or infinite plane of a charged conductor. When it is applied to magnetism, one side of the equation is zero because there is no such thing as a magnetic monopole. Additionally, it is closely related to Coulomb's Law.
