PhysicsEasysingle choice

The ratio between total acceleration of the electron in singly ionized helium atom and hydrogen atom (both in ground state) is

Options:

Answer:

Solution:

Required acceleration is given by centripetal acceleration.

$\Rightarrow$ $a = \frac{v^{2}}{r}$

$\Rightarrow$ $a \propto \frac{{(z)}^{2}}{(\frac{1}{z})}$

$a \propto z^{3}$

$∴ \frac{a_{1}}{a_{2}} = {(\frac{2}{1})}^{3} = 8$
