Suppose a region of space has a uniform electric field, directed towards the rig

Question

Suppose a region of space has a uniform electric field, directed towards the right, as shown in the figure. Which statement about the electric potential is true? A) The potential at all three locations (A, B, C) is the same because the field is uniform. B) The potential at point A is the highest, the potential at point B is the second highest, and the potential at point C is the lowest. C) The potential at points A and B are equal, and the potential at point C is lower than the potential at point A. D) The potential at points A and B are equal, and the potential at point C is higher than the potential at point A.

Explanation / Answer

correct answer.

The potential at points A and B is equal and the potential at point C is lower than the potential at point A

Explained

A and B are in what is called equipotential surface which is an imaginary line perpendicular to the electric field lines, therefore, they have the same potential

It is known that the electric field lines point toward the region of lower potential, thus the potential at C has a lower potential than A
