if the potential energy of a hydrogen atom in the ground state is assumed to be zero, then total energy of `n=oo` is equal to

A

`13.6 eV`

B

`27.2 eV`

C

zero

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
`U_1 = -27.2 eV`
`U_1` is assumed zero. Therefore, it is increased by
27.2 eV at all points.
`E_prop = 0` under normal conditions.
Hence, in charged conditions it is 27.2 ev.
