1. The problem statement, all variables and given/known data given a uniform electric field direct straight downward. If I have two particles, one is positive and the other is negative, both align horizontally (at the same height) inside the field. Which one has more electric potential? 2. Relevant equations 3. The attempt at a solution The electric field will try to push the positive particle in the same direction naturally if no force is applied. The electric potential is defined as the -integral of (E . dt) from very far to a certain location. Based on this, I say both particles have the same potential.
