Two particles of equal mass ‘m’ are projected from the ground with speed $V_1$ and $V_2$  at angles ${\theta }_1$  and ${\theta }_2$ as shown in fig. Given  ${\theta }_2>{\theta }_1$ and $V_1\cos {\theta }_1=V_2\cos {\theta }_2$ which statements is/are correct?

Particle ‘2’ will be above centre of mass level, when both particles are in air

Centre of mass of particles will move along a line inclined at some angle with vertical

Centre of mass of particles will move along a vertical line

Particle ‘1’ will be above centre of mass level, when both particles are in air
