A system consisting of two masses connected by a massles rod, lies along the X axis. A body of mass 0.4 kg is kept at a distnce `x=2m` and another body of mass 0.6 kg is kept at the distance `x=6` m from the origin. What is the x-coordinate of the centre of mass?

A

3m

B

4m

C

4.5m

D

4.4m

Text Solution

Verified by Experts

The correct Answer is:
D

`x=(m_(1)x_(1)+m_(2)x_(2))/(m_(2)+m_(2))`
`=(0.4xx2+0.6xx6)/(0.4+0.6)=(0.8+3.6)/(1)=4.4m`
