Figure shows a distance ring of radius R = 43.0 cm. Two small charged beads are on the ring : Bead 1 of charge `+20.0 mu C` is fixed in place at the left side , bead 2 of charge `+6.00 mu C` 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 `theta` should bead 2 be positioned such that `E= 2.00 xx 10^(5) N//C` ?

Explanation

(a) `67.8^(@)`, (b) `-67.8^(@)`
