A plastic ring of Radius R= 50.0 cm has two small charged beads on it. Bead 1 of charge +2.00 micro Coulombs is fixed in place on the left side of the ring. Bead 2 of charge +6.00 micro coulombs 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 positive and negative value of angle Theta should bead 2 be positioned such that E = 2.00 x 10^5 N/C?
