Two particles of equal mass '‘m'’ are projected from the ground with speeds v1 and v2 at angles θ1 and θ2 at the same time as shown in figure. The centre of mass of the two particles; Image not present (1) will move in a vertical line if v1 tan θ1 = v2 tan θ2 (2) will move in a vertical line if v1 sin θ1 = v2 sin θ2 (3) will move in a vertical line if v1 cot θ1 = v2 cot θ2 (4) will move in a vertical line if v1 cos θ1 = v2 cos θ2
