A `U`-shaped wire has a semicircular bending between `A` and `B` as shown in Fig. A bead of mass `m` moving with uniform speed `v` through a wire enters the semicircular bend at `A` and leaves at `B` with velocity `v//2` after time `T`. The average force exerted by the bead on the part `AB` of the wire is

A fixed U -shaped smooth wire has a semi-circular bending between A and B as shown in the figure. A bead of mass 'm' moving with uniform speed v through the wire enters the semicircular bend at A and leaves at B . The magnitude of average force exerted by the bead on the part AB of the wire is

A semicircular conducting wire of radius a is moving perpendicular to a uniform magnetic field B with speed √2 v as shown in the figure.The emf induced across the wire Is

A semicircular wire frame of radius R is standing vertical on a horizontal table. It is pulled horizontally towards right with a constant acceleration. A bead of mass m remain in equilibrium (relative to the semicircular wire) at a position where radius makes an angle q with horizontal. There is no friction between the wire and the bead. The bead is displaced a little bit in upward direction and released. Calculate the speed of the bead relative to the wire at the instant it strikes the table. Assume that all throughout the semicircular wire keeps moving with constant acceleration.
