The figure below shows a plastic ring of radius R =50.4 cm. Two small charged beads are on the ring: Bead 1 of charge+2.33 μC is fixed in place at the left side; bead 2 of charge+6.02 μC can be moved along the ring. The two beads produce anet electric field of magnitude E atthe center of the ring. At what (a) positiveand (b) negativevalue of angle θ shouldbead 2 be positioned such that E =2.25 × 105 N/C?
