Question

If the potential energy of a hydrogen atom in the first excited state is assumed to be zero, then the total energy of $n$ $=\infty$ state is,, $3.4 \mathrm{eV}$, $6.8 \mathrm{eV}$, 0, $\infty$

MARKS App · Accepted Answer

Hint : Potential energy in 1 st emited stage $\left(\mathrm{U}_2\right)=-6.8 \mathrm{eV}$. When $U_2$ is assumed to be zero then potential energy in $(n=\infty)$ will be $6.8 \mathrm{eV}$ so, total energy for $(n=\infty)=6.8 \mathrm{eV}$
