1. The problem statement, all variables and given/known data A uniform electric field between two parallel plates has magnitude of 20N/C and is directed downward. 1) A charge brought into this field experiences a force of 10.0 N downward. The charge must be....? 2) The potential energy of this charge when moving downward is...? 2. Relevant equations e = f/q 3. The attempt at a solution By using the equation, I found 0.5C. However, I am trying to get a picture of it. If the plate above is positive and the one below is negative...and the force is downward, would that mean the charge is positive? Then the answer for the second question means the charge is increasing. Would that be correct?
