A, B and C are three points in a uniform electric field. The electric potential is

1. maximum at B
2. maximum at C
3. same at all three points A, B and C
4. maximum at A

Correct answer: maximum at A

Solution

In a uniform electric field, the electric potential decreases in the direction of the field. Therefore, the point farthest opposite to the field direction (A) will have the maximum potential.
