In the gure particles 2 and 4, of charge e, are xed in place on a y axis, at Y2 = -10.6 cm and y4 = 5.30 cm. Particles 1 and 3, of charge -e, can be moved along the x axis. Particle 5, of charge +e, is xed at the origin. Initially particle 1 is at x1 = -10.6 cm and particle 3 is at x3 = 10.6 cm. (a) To what x value must particle 1 be moved to rotate the direction of the net electric force 17) net on particle 5 by 30 counterclockwise? (b) With particle 1 xed at its new position, to what x value must you move particle 3 to rotate back to its original direction
