let the potential energy of hydrogen atom in the ground state be zero.

1.	let the potential energy of hydrogen atom in the ground state be zero. then it's total energy in the first excited state will be
Answer» The total energy of hydrogen atom in GROUND STATE is −13.6eV. In first excited state total energy is −3.4eV. Now if POTENTIAL energy in ground state(−27.2) is taken as zero then the whole energy SPECTRUM will be shifted by 27.2eV.So, energy in first excited state will be:−3.4+27.2=23.8eV
