MCQ
The binding energy of a H-atom, considering an electron moving around a fixed nuclei $($proton$)$, is $\text{B}=-\frac{\text{me}^4}{8\text{n}^2\in_0^2\text{h}^2}. (m =$ electron mass$).$
If one decides to work in a frame of reference where the electron is at rest, the proton would be moving arround it. By similar arguments, the binding energy would be,
$\text{B}=-\frac{\text{me}^4}{8\text{n}^2\in_0^2\text{h}^2} (M =$ proton mass$)$
This last expression is not correct because:

This last expression is not correct because:
- An would not be integral.
- BBohr$-$quantisation applies only to electron.
- ✓The frame in which the electron is at rest is not inertial.
- DThe motion of the proton would not be in circular orbits, even approximately.
