A charged bead of charge q and mass m is threaded on a frictionless circular hoop of radius R in a horizontal plane. Another identical charge q is fixed at the top of the hoop. The bead is released from rest at the horizontal diameter position. Its speed when it reaches the bottom of the hoop is (assume the beads repel each other and use conservation of energy):
A √(kq²/(mR))
B √(2kq²/(mR))
C √(kq²/(2mR))
D 0
