Two particles of masses m_(1) and m_(2) and velocities u_(1) and alpha

1.	Two particles of masses m_(1) and m_(2) and velocities u_(1) and alpha u_(1)(alpha gt 0), make a elastic head on collision. If the initial kinetic energies of the two particles are equal and m_(1) comes to rest after collision, the
Answer» `(u_(1))/(u_(2)) = sqrt(2) + 1` `(u_(1))/(u_(2)) = sqrt(2)-1` `(m_(2))/(m_(1)) = 3+2sqrt(2)` `(m_(2))/(m_(1)) = 3-2sqrt(2)` ANSWER :A::C
