Electric field outside conductor

  1. Sep 21, 2016 #1
    1. The problem statement, all variables and given/known data
    A long metal pipe of square cross-section is grounded on three sides, while the fourth (which is insulated from the rest) is maintained at constant potential ##V_0##. What is the electric field just outside the section opposite to ##V_0##?

    2. Relevant equations


    3. The attempt at a solution
    This problem can possibly be solved by solving the Laplace equation under the given boundary condition. But is there any intuitive solution to this?

    You might want to post some type of drawing. However, I suspect you have a capacitance effect and that is probably your starting point.
