Determine whether or not each of the following statement is true. If a statement is true, prove it. If the statement is false, provide a counterexample and explain how it constitutes a counterexample. Diagrams can be useful in explaining such things.

If the electric potential in a certain region of space is constant, then the charge enclosed by any closed surface completely contained within that region is zero.

True

Explanation:

This is a representation of Gauss law.

Gauss's law does hold for moving charges, and in this respect Gauss's law is more general than Coulomb's law. In words, Gauss's law states that: The net outward normal electric flux through any closed surface is proportional to the total electric charge enclosed within that closed surface. The law can be expressed mathematically using vector calculus in integral form and differential form, both are equivalent since they are related by the divergence theorem, also called Gauss's theorem.
