(a) True

(b) False

The question was asked in class test.

I need to ask this question from System of Particles in chapter System of Particles and Rotational Motion of Physics – Class 11

Right choice is (b) False

The best I can explain: For momentum to be conserved its value should remain constant, but in projectile motion the force of gravity is always changing its momentum. The internal forces will break the particle and the momentum of different particles can be conserved in a direction perpendicular to direction of gravity.
