5. A +5 nC charge and a -5 nC charge are positioned as shown below. Draw the electric field lines and equipotential lines to help you solve this problem.
(a) Order points A to E in order of the electric potential, from lowest to highest.
(b) If you were to forcefully move a proton from any of the labeled points to any of the other labeled points, which path would require the most work?
(c) If you placed a motionless electron at point E and let go, in what direction would it accelerate?
