Applying Gauss's Law – University Physics Volume 2Charge Distribution with Spherical Symmetry. A charge distribution has spherical symmetry if the density of charge depends only on the distance from a point in space and not on the direction. In other words, if you rotate the system, it doesn't look different. For instance, if a sphere of radius R is uniformly charged with charge density then the distribution has spherical symmetry ((a)).
