Solve Laplace equation with boundary conditions

  1. Oct 26, 2008 #1
    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?

    Yes, you have two unknowns and two boundary conditions...what do you get for V?
