So, solving for Q in terms of ρ for the first case, I get Q = ρ3ϖR3 I plug this into the case I don't know, 2R, and I end up with E = (ρ3ϖR3)/(8ϖR2 ε0) I know I'm making an easy mistake but I can't pin down what it is.

Homework Statement A solid non-conducting sphere of radius R carries a uniform charge density. At a radial distance r1= R/4 the electric field has a magnitude Eo. What is the magnitude of the electric field at a radial distance r2=2R? Homework Equations Gauss's Law: ∫EdA=Qencl / ε0 Charge...

Homework Statement A charge Q is uniformly distributed throughout a nonconducting sphere of radius R. Write the expression of the charge density in the sphere? Homework Equations Charge density ρ=dQ/dV Gauss's Law ∫EdA = E(4ϖr^2) The Attempt at a Solution If Q is uniform then ρ=Q/dV and the...
