Four point charges of magnitude 6.00 μC and are at the corners of a square 2.00 m on each side.Two of the charges are positive,and two are negative.What is the electric potential at the center of this square,relative to infinity,due to these charges? (k = 1/4πε₀ = 8.99 × 10⁹ N ∙ m²/C²)

Since the charges at opposite corners are equal and opposite, their electric fields cancel out at the center of the square. The same is true for the other two charges at the remaining corners. Therefore, the net electric field at the center of the square is zero and the electric potential is also zero, relative to infinity.
