Question

Four point charges of equal magnitude are arranged at the corners of a square as shown in the figure. Positive charges are indicated by "+" and negative charges are indicated by "-". Select the only true statement about the electric potential at points a, b and c. The electric potential equals zero at points a and b, but not at point c. The electric potential equals zero at points a, but not at points b and c. The electric potential equals zero at points b and c, but not at point a. The electric potential equals zero at point c, but not at points a and b. The electric potential equals zero at point b, but not at points a and c. The electric potential equals zero at points a and c, but not at point b. The electric potential equals zero at none of these points. The electric potential equals zero at points a, b and c.
