`S_(1)` : Potential energy of the two opposite charge system increase with the decrease in distance .
`S_(2)` : When an electron makes transition from higher orbit to lower orbit it's kinetic energy increases.
`S_(3)` : When an electron make transition from lower energy to higher energy state its potential energy increases.
`S_(4)` : 11 eV photon can free an electron from 1 st excited state of `He^(+)` ion .
Select the correct set of true-false for above statements.

Options

A. `T T T T`
B. `F T T F`
C. `T F F T`
D. `F F F F`

Answer

B

Explanation

`S_(1)` : Potential energy of the two opposite charge system decreases with decrease in distance,
`S_(4)` : The energy of `1^(st)` excited state of `He^(+)` ion
`=-3.4 Z^(2)=-3.4xx2^(2)=-13.6 eV`.
`S_(2)` and `S_(3)` correct statement.
