If the distance between H and Cl ions in HCl molccule is x, then its moment of incrtia about an axis passing through the centre of mass and perpendicular to the bond length, is-

Options

A. `35x^(2)`
B. `36x^(2)//35`
C. `35x^(2)//36`
D. `x^(2)//35`

Answer

C

Explanation

`I=(m_(1)m_(2))/(m_(1)+m_(2)).x^(2)`
`I=(m_(H)m_(Cl))/(m_(H)+m_(Cl)).x^(2)`
`I=(35x^(2))/36`
