Question

In carbon monoxide molecule, the carbon and the oxygen atoms are separated by a distance $1.2\times {10}^{-10}m$. The distance of the center of mass, from the carbon atom, is

• A. $0.48\times {10}^{-10}m$
• B. $0.51\times {10}^{-10}m$
• C. $0.56\times {10}^{-10}m$
• D. $0.64\times {10}^{-10}m$

Answer 1

The correct option is D $0.64\times {10}^{-10}m$

From the definition of centre of mass.
$d=\frac{16\times 1.12\times {10}^{-10}+12\times 0}{16+12}=\frac{16\times 1.12{\times }^{-10}}{28}=0.64\times {10}^{-10}m$
