Question

Four point charges of equal magnitude are arranged at the corners of a square as shown in the fiqure. Positive charges are indicated by "+" and negative chargés are indicated by "-". Select the only true statement about the electric potential at points a, b and c o The electric potential equals zero at point b, but not at points a and c The electric potential equals zero at points a, b and c The electric potential equals zero at point c, but not at points a and b The electric potential equals zero at points b and c, but not at point a The electric potential equals zero at points a and b, but not at point 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, but not at points b and c Submit Answer Incorrect. Tries 2/4 Previous Tries What is the direction of the electric field at point b?
