The ground state and first excited state energies of hydrogen atom are `-13.6 eV` and `-3.4eV` respectively. If potential energy in ground state is taken to be zero. Then:
A. potential energy in the first excited state would be `20.4 ev `
B. total energy in the first excited state would be `23.8 eV`
C. kinetic energy in the first excited state would be `3.4 eV`
D. total energy in the ground state would be `13. 6 eV`
