Verified Solution • 2025–26 Session moderate

If an electron is moving in the n^th orbit of the hydrogen atom, then its velocity (v_n) for the n^th orbit is given as :

Accepted Answer

We know velocity of electron in n^th shell of hydrogen atom is given by

v = \frac{2 π k Z e^{2}}{n h}

∴

v \propto \frac{1}{n}
