5. (Problem 19-85) A square with sides of length L has a point charge at each of its four corners. Two corners that are diagonally opposite have charges equal to +3.25 uC; the other two diagonal corners have charges Q. Find the magnitude and sign of the charges such that each of the +3.25 C charges experiences zero net force. (Hint: Think of the sign of the charges Q first. And then find out its magnitude.)
