For the special case of a point charge, it reduces to Coloumb's law.
Bouguer's formula is an analog of this for gravitational fields. To use it with an infinite line, a cylindrical surface known as its namesake's "pillbox" is formed. For the special case of a point charge, it reduces to Coloumb's law. For more complex geometries, a surface integral of E dot d A is calculated. One of Maxwell's equations, for ten points, name this law that states that the enclosed charge divided by the permittivity is equal to the electric flux through a closed surface.
