by Symmetry: The Three Cases

Charge distributions of three and only three types produce a flux that is uniform or zero for all parts of an appropriately chosen Gaussian surface: centro-symmetric charge distributions with spherical, cylindrical, and planar symmetry. Gauss's law and a knowledge of the charge then enables us to deduce the magnitude of the electric field; we simply apply (4.11). (A cube that is concentric with a point charge has some symmetry; each of its faces picks up the same flux, which is one-sixth of the total flux. However, the

field is not uniform over each face, so that we can only obtain the average flux for each face, rather than the electric field itself.)
