1. The problem statement, all variables and given/known data A solid sphere contains a uniform volume charge density (charge Q, radius R). (a) Use Gauss’s law to find the electric field inside the sphere. (b) Integrate E^2 over spherical shells over the volumes inside and outside the sphere. (c) What fraction of the total electrostatic energy of this configuration is contained within the sphere? 2. Relevant equations [Broken] Qenclosed = r^3/R^3 flux= 4pi*r^2*E 3. The attempt at a solution a) E=(Q*r)/(4*pi*(epsilon0)*R^3) b) So I am thinking for this one that I need to integrate E^2 with upper limits being inside and lower limits being the outside of the sphere. what I'm not sure is if its intergral(E^2 dE) or if a value inside of E is being integrated. R or r would make sense to intergrate as well hence intergral(E dr) c) since I can't solve b, I can't solve c either.
