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 xx 10^(-10)`m
B. `0.51 xx 10^(-10)`m
C. `0.56 xx 10^(-10`m
D. `0.69 xx 10^(-10)`m

Answer

D

Explanation

Distance distributes in inverse ratio of masses.
Here, `r_(c) = d(m_(0))/(m_(0)+m_(c)) = 1.2 xx 10^(-6)(16/(16+2))`
`0.069 xx 10^(-10)`m
