Question

Suppose the potential energy between electron and proton at a distance r is given by --$\frac{k{e}^2}{r}$. The value of -($V_n/K_n)$ is : (Use Bohr's theory)

Answer 1

$V_n=-\frac{1}{4\pi {ϵ}_0}\left(\frac{Z{e}^2}{r}\right)$
$K_n=\frac{1}{8\pi {ϵ}_0}\left(\frac{Z{e}^2}{r}\right)$

$-\frac{V_n}{K_n}=2$
