WebJan 8, 2024 · I have come across the differential form of Gauss's Law. ∇ ⋅ E = ρ ϵ 0. That's fine and all, but I run into what I believe to be a conceptual misunderstanding when … WebCALC. A metal sphere with radius r_a is supported on an insulating stand at the center of a hollow, metal, spherical shell with radius r_b. There is charge +q on the inner sphere and charge -q on the outer spherical shell. (a) Calculate the potential V(r) for (i) r r_b. (Hint: The net potential is the sum of the potentials due to the individual spheres.)
