Question

The ratio of total acceleration of the electron in singly ionized helium atom in ground state and hydrogen atom (in ground state) according to bohr model is $x$ then $x$ is

Answer 1

$a=\frac{V^2}{r}$

$a\propto \frac{Z^2}{\frac{1}{Z}}\Rightarrow a\propto Z^3$

$\frac{a_1}{a_2}={\left(\frac{2}{1}\right)}^3=8$
