Two projectiles arc thrown simultaneously in the same plane from the same point. If their velocities are
P \( v_{1} \) and \( v_{2} \) at angles \( \theta_{1} \) and \( \theta_{2} \) respectively from the horizontal, then answer the following questions.
If \( v_{1} \cos \theta_{1}=v_{2} \cos \theta_{2} \), then choose the incorrect statement
(1) One particle will remain exactly below or above the other particle
(2) The trajectory of one with respect to other will be a vertical straight line
(3) Both will have the same range
(4) None of these
