The correct option is:
(b) M = mproton $+$ melectron $-B / c^{2}(B=13.6 \mathrm{eV})$
The gravitational force between an H-atom and another particle of mass m will be given by Newton’s law: $F=GMm/r^{2}$, where r is in km and
(a) M = mproton + m electron
(b) M = mproton $+$ melectron $-B / c^{2}(B=13.6 \mathrm{eV})$
(c) M is not related to the mass of the hydrogen atom
(d) M = mproton +melectron $|\mathrm{V}| / \mathrm{c}^{2}-(|\mathrm{V}|=$ magnitude of the potential energy of electron in the $\mathrm{H}$-atom)
(a) M = mproton + m electron
(b) M = mproton $+$ melectron $-B / c^{2}(B=13.6 \mathrm{eV})$
(c) M is not related to the mass of the hydrogen atom
(d) M = mproton +melectron $|\mathrm{V}| / \mathrm{c}^{2}-(|\mathrm{V}|=$ magnitude of the potential energy of electron in the $\mathrm{H}$-atom)
