Question

A molecule is made up of two atoms of equal mass $m$. These two atoms are separated by a distance $a$. The moment of inertia to the molecule about an axis perpendicular to the line joining the atoms and passing through either of the two atoms is-

• A. $m{a}^2$
• B. $2m{a}^2$
• C. $\frac{1}{2}m{a}^2$
• D. $\frac{1}{4}m{a}^2$

Answer 1

The correct option is A $m{a}^2$

Hence, option $A$ is correct answer.
