A wire, which passes through the hole in a small bead, is bent in the form of quarter of a circle. The wire is fixed vertically on ground as shown in the figure. The bead is released from near the top of the wire and it slides along the wire
without friction. As the bead moves from A to B, the force it applies on the wire is
without friction. As the bead moves from A to B, the force it applies on the wire is
