The distance between the centres of carbon and oxygen atoms in the carbon monoxide molecule is 1.139 `overset(@)(A)`. Locate the centre of mass of the molecule relative to the carbon atom :

Options

A. `5.428 overset(@)(A)`
B. `1.130 overset(@)(A)`
C. `0.6457 overset(@)(A)`
D. `0.3260 overset(@)(A)`

Answer

C

Explanation

`x_(CM)=(m_(1)x_(1)+m_(2)x_(2))/(m_(1)+m_(2))`

`therefore x_(CM)=((12 times0)+(16 times1.13))/(12+16)=0.6457 overset(@)(A)`
