1. The problem statement, all variables and given/known data I am needing help with just a conceptual question. I am wondering how the field magnitude varies with the distance between the field lines and if it remains constant along a line of force. 2. Relevant equations I don't think I use an equation. Maybe Coulomb's equation. 3. The attempt at a solution I am not for sure how to solve it so I don't know a solution I guess. I think though that the field magnitude is constant if the charges are kept the same. Am I on the right path?
