In the diagram, the points 1, 2, and 3 are all the same very large distance from a dipole.Rank the points according to the values of the electric potential at them, from the most negative to the most positive.

Question

Quizplus · Accepted Answer

The electric potential due to a dipole decreases as the distance from the dipole increases. Since all three points are at the same distance from the dipole, the electric potential at all three points is the same. However, the electric potential due to a dipole is more negative at points closer to the negative charge and more positive at points closer to the positive charge. Therefore, the point closest to the negative charge (point 1) will have the most negative electric potential, followed by the point farthest from the positive charge (point 3) with a less negative potential, and finally the point in the middle (point 2) with a potential between the other two. Thus, the ranking is 1, 3, 2 or D.
