The ground state and first excited state...

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 `20.4eV`

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`
