1. The problem statement, all variables and given/known data A charge Q is uniformly distributed throughout a nonconducting sphere of radius R. Write the expression of the charge density in the sphere? 2. Relevant equations Charge density ρ=dQ/dV Gauss's Law ∫EdA = E(4ϖr^2) 3. The attempt at a solution If Q is uniform then ρ=Q/dV and the volume of a sphere is 4/3ϖr^3 then I think charge density would just be ρ=Q/(4/3ϖr^3). This is suspiciously simple so I would just like external input on the problem. I have a feeling that I may need to use Gauss's Law somehow.
