Two beads `A` and `B` of masses `m_(1)` and `m_(2)` respectively, are threaded on a smooth circular wire of radius a fixed in a vertical plane. `B` is stationary at the lowest point when `A` is gently dislodged from rest at the highest point. A collided with `B` at the lowest point. The impulse given to `B` due to collision is just great enough to carry it to the level of the centre of the circle while `A` is immediately brought to rest by the impact.
What is the coefficient of restituting between the beads?

A

1

B

`1//2`

C

`1//3`

D

`1//sqrt(2)`
