Figure 22-43 shows a plastic ring of radius R 50.0 cm. Two small charged beads are on the ring: Bead 1 of charge 2.00 mC is fixed in place at the left side; bead 2 of charge 6.00 mC can be moved along the ring. The two beads produce a net electric field of magnitude E at the center of the ring. At what (a) positive and (b) negative value of angle u should bead 2 be positioned such that E 2.00 105 N/C?
