2 bodies of different masses of 2 kg and 4 kg are moving with velocities `20 m//s` and 10 m//s towards each other due to mutual gravitational attraction. What is the velocity of their centre of mass?

`5 ms ^(-1)`

`6 ms ^(-1)`

`8 ms ^(-1)`

Zero

Text Solution

Verified by Experts

Velocity of centre of mass is not affercted as ganiration force are mutual.
