The inverse square law in electrostatics is for the force between an electron and a proton. The (1/r) dependence of | | F can be understood in quantum theory as being due to the fact that the ‘particle’ of light (photon) is massless. If photons had a mass mp, force would be modified to . What is the estimated change in the ground state energy of a hydrogen atom if the proton mass (m p ) were 10 -6 times the mass of a
