Question 465: Atoms & Nuclei

Question

Ratio centripetal acceleration for an electron revolving in 3
rd
and 5
th
Bohr orbit of hydrogen atom is

Accepted Answer

Centripetal acceleration $$a=\frac{v^2}{r}$$
For hydrogen atom, $$V \propto \frac{1}{\mathrm{n}}$$ and $$\mathrm{r} \propto \mathrm{n}^2$$
$$	herefore a \propto \frac{1}{n^4} \quad 	herefore \frac{a_2}{a_5}=\left(\frac{5}{3}ight)^4=\frac{625}{81}
$$
