1. Problem: Electric Potential due to Point Charges Consider four point charges placed at the corners of a square of side s = 0.5 μm. Two charges, diagonally opposite each other, are +0.7 nC. Another of the charges is -12 nC. a) What will be the electric potential at the center of the square if the fourth charge is -6 nC (assume the conventional zero point definition for each individual charge throughout this problem)? b) What should the fourth charge...
