Q)

The energy of an electron in the first Bohr orbit of H atom is −13.6eV . The possible energy value(s) of the excited state(s) for electrons in Bohr orbits to hydrogen is(are)

$\begin{array}{1 1}(a)\;−3.4eV\\(b)\;−4.2eV\\(c)\;−6.8eV\\(d)\;+6.8eV\end{array}$

A)
Values of energy in the excited state
$=\frac{−13.6}{n^2} eV$
$=\frac{−13.6}{4}= −3.4eV$
in which n=2,3,4 etc.
