4. Three point charges lie along the y-axis. The first charge q = -9C is at y = 6.0-m. The second charge, q2 = -8C is at y= -4.0-m. At what point on the y-axis must the third positive charge be placed so that the net force on it is zero? 4. Three point charges lie along the y-axis. The first charge q = -9C is at y = 6.0-m.
