The gravitational force between a H-atom...

The gravitational force between a H-atom and another particle
of mass m will be given by Newton's law:
`F=G(M.m)/r^2`, where r is in the km.

A

`M=m_(proton)+m_(electron)`.

B

`M=m_(proton)+m_(electron) -B/c^2(B=13.6eV)`

C

M is not related to the mass of the hydrogen atom.

D

`M=m_(proton)+m_(electron) -|V|/c^2(|V|)`=magnitude of the
potential energy of electron in the H-atom.
