Question:

Consider a point midway between the two large charged plates in Fig. 16.27. Compute the change in electric potential if from there you moved
(a) 1.0 mm toward the positive plate,
(b) 1.0 mm toward the negative plate, and
(c) 1.0 mm parallel to the plates. What do your answers tell you about the direction of the electric field in that region?
