Two particles A and B are thrown simultaneously from two different floors of tower having distance d between them.Velocitiy of particle A is `v_(A)` at angle `alpha` from horizontal while velocity of particle B is `v_(B)` at an angle `beta` from horizontal.If two particles collide in mid-air,then find `v_(A)/v_(B)`.

Two particles A and B are thrown simultaneously from two different floors of tower having distance d between them. Velocities of particle A is v_(A) at angle alpha from horizontal while velocities of particle B is v_(B) at an angle beta from horizontal. If two particles collide in mid-air, then v_(A)/v_(B) .
