\(\therefore\)  \(n = 2\)

કોણીય વેગમાન \( = \,\,\frac{{nh}}{{2\pi }}\,\, = \,\,\frac{{2h}}{{2\pi }}\,\, = \,\,\frac{h}{\pi }\,\)

ઉર્જા \( = \,\,\frac{{ - 2{\pi ^2}m{e^4}{z^2}}}{{{n^2}{h^2}}}\,\, = \,\,\frac{{ - 2{\pi ^2}m{e^4}{{(3)}^2}}}{{{{(2)}^2}\,({h^2})}}\,\,{\text{[ Li }}\) માટે \({\text{Z  =  3]}}\)\( = \,\,\frac{{ - 9{\pi ^2}\,m{e^4}}}{{2{h^2}}}\)
