Two particles are shown in figure. At t = 0, a constant force F = 6N starts acting on the 3 kg mass.

A particle of mass 2m is projected at an angle of 45° with horizontal with a velocity of 20√2 m/s. A

Two bodies of mass 3 kg and 5 kg have their centre of mass at origin. If 3 kg is at a distance of 5
