Four point charges of magnitudes +3q, -q, +2q, and -2q are arranged in the corners of a square of side length L., The charge –q creates a potential of 1 V (relative to infinity) in the center of the square.

What is the total potential created in the center of a square by all 4 charges?

1V

It is impossible to determine without knowing the exact arrangement.

10 V

5 V

0 V
