(choose chapter or problem)

In Fig. 21-33, 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 on particle 5 by 30" counterclockwise? (b) With particle 1 fixed at its new position, to what x value must you move particle 3 to rotate back to its original direction? y 1 3 4 2 Figure 21-33 29
