A particle A is projected with speed `v_(A)` from a point making an angle `60^(@)` with the horizontal. At the same instant, a second particle B is thrown vertically upwards from a point directly below the maximum hieght point of parabolic path of A with velocity `v_(B)`. If the two particles collide then the ratio of `v_(A)//v_(B)` should be
