2. Figure below shows a plastic ring of radius R = 50.0 cm. Two small charged beads are on the ring: Bead 1 of charge +2.00 µC is fixed in place at the left side; bead 2 of charge +6.00 µC 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 = 2.00 ×10$ N/C? Bead 2 Bead 1 Ring
