Four particles with charges of 8.1 µC, 4.1 µC,4.7 μC, and -14 µC are placed at the corners of a 2.9 m x 2.9 m square.Determine the potential difference between the center of the square and infinity. The acceleration due to gravity is 9.81 m/s²and the value of the Coulomb constant is8.98755 × 10⁹ Nm²/C².Answer in units of V.
