In a carbon monoxide molecule, the carbon and the oxygen atoms are separated by a distance `1.2xx10^-10m`. The distance of the centre of mass from the carbon atom is

Options

A. `0.48 xx10^(-10) m`
B. `0.51xx10^(-10) m`
C. `0.56 xx10^(-10) m`
D. `0.69xx10^(-10) m`

Answer

D

Explanation

Distance distributes in inverse ratio of masses.
Hence, `r_(c)=d(m_(0)/(m_(0)+m_(c)))=1.2 xx10^(-10) (16/(16+12))`
`=0.69xx10^(-10) m`
