Homework Statement Determine the total electrostatic potential energy of a nonconducting sphere of radius r0 carrying a total charge Q distributed uniformly throughout its volume. Express your answer in terms of the variables Q, r0, and appropriate constants. Homework Equations V = kQ/r...

I just did a) again: ∫E dA = Q_enc/ε_0 E(4πr^2) = [ρ((4/3)π(r/R_1)^3)]/[ε_0] E = (ρr)/(3(ε_0)(R_1)^3) Does that seem right?

Ok. Here's my work: For a), my gaussian surface is between the two shells For b), my gaussian surface is outside both shells a) ∫E dA = Q_enc/ε_0 E(4πr^2) = [ρ((4/3)π(R_1)^3)]/[ε_0] E = [ρ((4/3)π(R_1)^3]/[(ε_0)(4πr^2)] E = [ρ(R_1)^3]/[3(ε_0)(r^2)] b)∫E dA = Q_enc/ε_0 E(4πr^2) =...
