In a carbon monoxide molecule, the carbon and the oxygen atoms are separted by a distance ` 1.12 xx 10^(10)` m. The distance of the centre of mass from the carbon atom is

Options

A. `0.64xx10^(-10)m`
B. `0.56xx10^(-10)m`
C. `0.51xx10^(-10)m`
D. `0.48xx10^(-10)m`

Answer

A

Explanation

From definition of centre of mass.
`d=(16xx1.12xx10^(-10)+12xx0)/(16+12)=0.64xx10^(-10)m`.
