if we assume only gravitational attraction between proton and electron in hydrogen atom and the Bohr quantizaton rule to be followed, then the expression for the ground state energy of the atom will be (the mass of proton is M and that of electron is m.)

If we assume only gravitational attraction between protect and electron in hydrogen atom and the Bohr's quantization rule kto be allowed , then the expression for the ground state energy of the atom will be (the mass of proton is M and that of electron is m )

Total energy of an electron in a ground state of hydrogen atom will be—

The total energy of an electron in the ground state , of hydrogen atom is

Calculate the energy of the electron in the ground state of the hydrogen atom.

The velocity of an electron in the ground state of hydrogen atom in m/sec is

State the location of electrons, protons, protons and neutrons in an atom.

The average separation between the proton and the electron in a hydrogen atom in ground state is 5.3xx10^-11m . a. Calculate the Coulomb force between them at this separation.
