A region of space contains a uniform electric field, directed toward the right, as shown in the figure. Which statement about this situation is correct?

Question

Quizplus · Accepted Answer

Since the electric field is directed toward the right, the potential decreases as we move from left to right. Therefore, the potential at point C, which is the farthest right, is the lowest. Since points A and B are at the same distance from the right edge of the region, their potentials must be the same. However, since point C is farther right than points A and B, its potential must be lower. Therefore, the correct choice is C.
