Two balls are projected simultaneously in the same vertical plane from

1.	Two balls are projected simultaneously in the same vertical plane from the same point with velocities V1 and V2 with angles θ1 and θ2 respectively with the horizontal. If V1 cosθ1 = V2 cosθ2 the path of one ball as seen from the position of other ball is1) Parabola 2) Horizontal straight line 3) Vertical straight line 4) Straight line making 45° with the vertical
Answer» Correct :-(3) Explanation :- It is given that V₁cos θ₁ = V₂cos θ₂ . Hence the relative velocity between them is zero. The path of one ball as seen from the position of the other ball is vertical straight line.
