Problem B12: Consider the infinitely long solid cylinder shown in the figure above. The cylinder has a radius R, and has a uniform charge volume density of n₁ ρ₀ > 0. What is the voltage difference between a point located a distance of r = R/n₂, labeled "b", and the center of the cylinder, labeled "a"? That is if V(a)-V(b) = ρ₀R²/(ε₀ n₃), what is n₃ ?
