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.
