1. The problem statement, all variables and given/known data Consider uniform electric field. The values of the potentials at the points(0,0) (.5,0) are equal and 20V higher than the potential at (0,.5) The magnitude and direction of the electric field are: a)0 b)40N/c j c)-40N/c j 2. Relevant equations 3. The attempt at a solution I know the answer is b because this is a problem for my exam review and we were given the solutions, I don't know how to get it though can anyone help?
