1. The problem statement, all variables and given/known data Calculate potential function and the electric field for the region between two concentric cylinders, where V ( inner cylinder) = 0 at r = 0.015 m and V(outer cylinder) = 100 for r = 0.025 2. Relevant equations [tex]\Delta[/tex] (square ) V = 0 3. The attempt at a solution so, V depends only on s, and we will just end up having two unknowns and we will need two boundary conditions that we already have. am i right?
