n=4 and energy of 4 text th orbit is -0.85 eV

Q. In a sample of H-atoms, electrons de-excite from a level $n$ to 1 . The total number of lines belonging to Balmer series are $2.$ If the electrons are ionised from level $n$ by photons of energy $13 e V$ , then the kinetic energy (in $e V$ ) of the ejected photoelectrons will be

$n = 4$ and energy of $4^{th}$ orbit is $- 0.85 e V$
