A Hydrogen atom and `Li^(++) ion` are both in the second excited state . If `l_(H) ` and `l_(Li)` are their respective energies, thenA. `l_(H) gt l_(L I) and |E_(H) | gt |E_(L I)|`B. `l_(H) = l_(L I) and |E_(H) | lt |E_(L I)|`C. `l_(H) = l_(L I) and |E_(H) | gt |E_(L I)|`D. `l_(H) = l_(L I) and |E_(H) | lt |E_(L I)|`

Answer» Correct Answer - B
`L = (n h)/(2 pi), |E| prop Z^(2)//n^(2) : n = 3`
`implies L_(H) = L_(Li) and |E_(H)| lt |E_(LI)|`
