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)`.

A

`(cosbeta)/(cosalpha)`

B

`(sinalpha)/(sinbeta)`

C

`(tanalpha)/(tanbeta)`

D

`(cotalpha)/(cotbeta)`
