Assertion:- Two stones are simultaneously projected from level ground from same point with same speeds but different angles with horizontal Both stones move in same vertical plane. Then the two stones may collide in mid air. Reason:- For two stones projected simultaneously from same point with same speed at different angles with horizontal, their trajectories must intersect at some point except projection point.
