Q: The gravitational force between a 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 + melectron
(b) M = mproton + melectron -B/C2 (B = 13.6 eV)
(c) M is not relate to the mass of the hydrogen atom.
(d) M = mproton + melectron -|V|/C2 ; (|V| = magnitude of the potential energy of electron in the H-atom.
