For an infinitely long nonconducting cylinder of radius R, which carries a uniform volume charge density , calculate the electric field at a distance r < R. I did: e = E d A = Q i n 0, where I'm measuring A to be the area of the Gaussian surface (not the real cylinder). Thus, by dividing the total flux by six surfaces of a cube we can find the flux . dS is an increment of the surface area (meter2). The law was formulated by Carl Friedrich Gauss (see ) in 1835, but was not published until 1867. \end{align} Gauss Law claims that a closed surface's total electric flux is equivalent to the enclosed charge of that surface divided by permittivity. Electric flux depends on the strength of electric field, E, on the surface area, and on the relative orientation of the field and surface. The two circles on either end cannot be part of a gaussian surface because they do not have a constant electric field, and the electric field is not perpendicular to the circles.
