One energy difference between the states...

One energy difference between the states `n = 2` and `n= 3` is `"E eV"`, in hydrogen atom. The ionisation potential of `H` atom is -

A

`3.2E`

B

`7.2E`

C

`5.6E`

D

`13.2E`

Text Solution

Verified by Experts

The correct Answer is:
B
`(E_(1))/(3^(2)) -(E_(1))/(2^(2)) = E rArr (-5E_(1))/(36) = E, E_(1) = - 7.2E`
`I.E. +E_(1) = +7.2E`
