A projectile A is thrown at an angle `30^(@)` to the horizontal from point P. At the same time, another projectile B is thrown with velocity `v_(2)` upwards from the point Q vertically below the highest point A would reach. For B to collide with A the ratio `(v_(2))/(v_(1))` should be

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
