(6) 1. Four point charges q1 = q2 = 93 = 94 = 32.OuC are arranged as in the figure below. Let d = 5.20cm. a) If you place a fifth charge, q5, at the origin, what must be the magnitude of this charge such that the system is in equilibrium? b) How does the magnitude of q5 change if you were to change the side length of the square? y 94 91 (-d,d) (d,d) X 92 93 (d,-d) (-d,-d)
