Two particles of masses `m_(1)` and `m_(2)` and velocities `u_(1)` and `alphau_(1)(alpha!=0)` make an elastic head on collision. If the initial kinetic energies of the two particles are equal and `m_(1)` comes to rest after collision, then

A

`(u_(1))/( u_(2)) = sqrt(2) + 1`

B

`(u_(1))/( u_(2)) = sqrt( 2) - 1`

C

`(m_(2))/( m_(1)) = 3+ 2sqrt(2)`

D

`(m_(2))/(m_(1)) = 3- 2 sqrt(2)`
