Question:
The gravitational force between an H-atom and another particle of mass m will be given by Newton’s law: F = G M.m/r2 , where r is in km and
(a) M = mproton + m electron
(b) M = mproton + melectron – B/c2 (B = 13.6 eV)
(c) M is not related to the mass of the hydrogen atom
(d) M = mproton + m electron |V |/c2 – (|V | = magnitude of the potential energy of electron in the H-atom)
Solution:
(b) M = mproton + melectron – B/c2 (B = 13.6 eV)
