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

A particle A is projected with speed V_(A) from a point making an angle 60^(@) with the horizontal. At the same instant, second particle B( lie in the same horizontal plane ) is thrown vertically upwards from a point directly below the maximum height 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 :

A particle is projected with a speed V from a point O making an angle of 30^(@) with the vertical. At the same instant, a second particle is thrown vertically upwards with a speed v from a point A. The two particle reach H, the highest point own the parabolic path of particle one simultaneously. Then ratio V/v is-

A particle P is projected with velocity u_1 at an angle of 30^@ with the horizontal. Another particle Q is thrown vertically upwards with velocity u_2 from a point vertically below the highest point of path of P . Determine the necessary condition for the two particles to collide at the highest point. .
