NEETPhysicsRotational Motion
In the HCl molecule, the separation between the nuclei of the two atoms is about 1.27 Å . What is the approximate location of the CM of the molecule, given that a chlorine atom is about 35.5 times as massive as a hydrogen atom and nearly all the mass of an atom is concentrated in its nucleus.
Options
- Athe centre of mass of the HCl molecule lies 0.027 A˚ from the Cl atom
- Bthe centre of mass of the HCl molecule lies 0.035 A˚ from the Cl atom
- Cthe centre of mass of the HCl molecule lies 0.065 A˚ from the Cl atom
- Dthe centre of mass of the HCl molecule lies 0.073 A˚ from the Cl atom
Correct answer
B. the centre of mass of the HCl molecule lies 0.035 A˚ from the Cl atom
Step-by-step solution
Correct Option is : (B) the centre of mass of the HCl molecule lies 0.035 A˚ from the Cl atom
