The absence of net charge and momentum would follow from accepted physical laws ( Gauss's law and the non-divergence of the stress-energy-momentum pseudotensor, respectively ), if the universe were finite.
Coulomb's law is actually a special case of Gauss's Law, a more fundamental description of the relationship between the distribution of electric charge in space and the resulting electric field.
While Columb's law ( as given above ) is only true for stationary point charges, Gauss's law is true for all charges either in static or in motion.
Gauss's law allows the E-field to be calculated in terms of a continuous distribution of charge density

Gauss's and gives
Gauss's inequality gives an upper bound on the probability that a value lies more than any given distance from its mode.
Gauss's and between
The suitability of Stirling's, Bessel's and Gauss's formulae depends on 1 ) the importance of the small accuracy gain given by average differences ; and 2 ) if greater accuracy is necessary, whether the interpolated point is closer to a data point or to a middle between two data points.
It follows from an application of Gauss's Lemma that if A is the norm of then the distance, induced by the metric, between two close enough points on the curve γ, say γ ( t < sub > 1 </ sub >) and γ ( t < sub > 2 </ sub >), is given by

Gauss's and electric
This quantity arises in Gauss's law-which states that the flux of the electric field E out of a closed surface is proportional to the electric charge Q < sub > A </ sub > enclosed in the surface ( independent of how that charge is distributed ), the integral form is:
In physics, Gauss's law, also known as Gauss's flux theorem, is a law relating the distribution of electric charge to the resulting electric field.
Gauss's law can be used to demonstrate that all electric fields inside a Faraday cage have an electric charge.
Gauss's law can be stated using either the electric field E or the electric displacement field D. This section shows some of the forms with E ; the form with D is below, as are other forms with E.
Since the flux is defined as an integral of the electric field, this expression of Gauss's law is called the integral form.
If the electric field is known everywhere, Gauss's law makes it quite easy, in principle, to find the distribution of electric charge: The charge in any given region can be deduced by integrating the electric field to find the flux.
Magnetic field lines only exist as loops, they cannot diverge from or converge to a point like electric field lines can ( see Gauss's law for magnetism ).
Gauss's and flux
