If multiple situations rank equally, use the same rank for each, then exclude the intermediate ranking (i.e. if objects A, B, and C must be ranked, and A and B must both be ranked first, the ranking would be A:Greatest, B:Greatest, C:Third greatest). If all situations rank equally, rank each as 'Greatest'.

Two small charged beads are on the ring: Bead 1 of charge +2.33 JC is fixed in place at the left side; bead 2 of charge +6.01 JC 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 0 should bead 2 be positioned such that E = 2.34 x 105 N/C?
