The figure shows a plastic ring of radius R = 50.4 cm. Two small charged beads are on the ring: Bead 1 of charge +2.34 μC is fixed in place at the left side; bead 2 of charge +6.09 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 θ should bead 2 be positioned such that E = 2.06 × 105 N/C?

A bead of mass m is made to slide around on a ring of radius R standing on its side. The bead is attached to one end of a spring with string constant k, and the other end of the spring is attached to one point on the ring, halfway up one side. There is gravity, g, and you may ignore friction. For simplicity, we will assume that the equilibrium length of the spring (when it has no tension) is...
