1.	Two bodies of masses 2 kg and 4 kg are moving with velocities 2 m s^(-1) and 10 m s^(-1) towards each other due to mutual gravitational attraction. What is the velocity of their centre of mass?
Answer» `5.3 m s^(-1)` `6. 4 m s^-1` ZERO `8 . 1 m s^-1` Solution :Under mutual gravitional ATTRACTION , the centre of mass remains at rest .
