Homework Help: Conductors and electric field problem

  1. Sep 23, 2010 #1
    1. The problem statement, all variables and given/known data

    What would the electric field lines look like if two opposite charges were placed within an infinite plane conductor?



    2. Relevant equations

    None that I am aware of.



    3. The attempt at a solution

    I know that electric field is 0 inside of the conductor. I know that if a single charge was in the conductor, that the electric field would be the same as the charge would normally emanate outside of the conductor. However I am having trouble visualizing what two opposite charges electric field would look like. Originally I thought that the electric field would look almost like a magnetic field due to the two opposite charges. I also wonder though if the two charges would cancel and there be no electric field outside of the conductor.

    Re: Conductors

    The charges of a dipole cancel yet it has a field at almost all points in space.

    Ok. That seems to make sense to me. That seems more in line with my original train of thought. Thanks!
