To solve this problem we will apply the concept of voltage given by Coulomb's laws. From there we will define the charges and the distance, and we will obtain the total value of the potential difference in the system.
The length of diagonal is given as
The distance of the center of the square from each of the corners is
The potential electric at the center due to each cornet charge is
The total electric potential at the center of the given square is
Al the charges are equal, and the distance are equal to a, then
Therefore the correct option is E.
