1. The problem statement, all variables and given/known data Is it possible to use Gauss' law to find intensity of a spherical charge distribution where the charge distribution (i)is non-homogeneous in general...i.e. dependent on (r,theta,phi) (ii)can be thought of as a made up of concentric spherical shells of different densities? 2. Relevant equations 3. The attempt at a solution (i) I think -No.As the distribution varies with (r,theta,phi) the spherical symmetry is destroyed---the spherical layers should encounter the field lines symmetrically.But that is not allowed here. (ii)the spherical layers should encounter the field lines symmetrically.So,here it is allowed. Please confirm if I am correct.
