A particle is projected vertically upwards in vacuum with a speed u .

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. .
