In Figure particles 2 and 4, of charge e, are fixed in place on a y axis, at y2 = 10.0 cm and y4 = 5.00 cm. Particles 1 and 3, of charge e, can be moved along the x axis. Particle 5, of charge e, is fixed at the origin. Initially particle 1 is at x1 = 10.0 cm and particle 3 is at x3 = 10.0 cm.
(a) To what x value must particle 1 be moved to rotate the direction of the net electric force F net on particle 5 by 30o counterclockwise?
(b) With particle 1 fixed at its new position, to what x value must you move particle 3 to rotate f net back to its originaldirection?
