magine a square with sides of length d = 1.90 meters. At three of the corners of the square are charges with magnitude Q1. At one corner of the square is a single charge Q2. Draw a diagram of the square, and label the charges at each corner Q1 or Q2 as appropriate. If Q1 = +28.1 microCoulombs, and Q2 = +23.1 microCoulombs, (a) If the electric potential is zero infinitely far away, what is the value of the electric potential at the center of the square? (b) How much work would you have to do to bring a proton from very far away to the center of the square? (c) Explain what the sign of your answer to part (b) means in this case. What would be different if the sign had come out differently?
