An electron of a stationary hydrogen atom passes from the fifth energy level to the ground level. The velocity that the atom acquired as a result of photon emission will be :
($\displaystyle m$ is the mass of the electron, $\displaystyle R$, Rydberg constant and $\displaystyle h$ Planck's constant)
Official answer
(3)
$\displaystyle \frac{24 \mathrm{~h} \mathrm{R}}{25 \mathrm{~m}}$
