The absolute potential at the center of a square is 3. V when a charge of +Q is located at one of the square's corners. What is the absolute potential at the square's center when a second charge of -Q is placed at one of the remaining corners?

Question

The potential due to a positive charge is positive, and the potential due to a negative charge is negative. Since the magnitudes of the charges are the same, the potentials they create at the center of the square will have the same magnitude but opposite signs, canceling each other out, resulting in a net potential of zero.
