Question

Calculate the velocity of an electron placed in the third orbit of hydrogen atom. Also calculate the number of revolutions per second that this electron mkaes around the nucleus.

Answer 1

$V=2.18\times {10}^6\times \frac{z}{n}$

$V=2.18\times {10}^6\times \frac{1}{3}=7.26\times {10}^{5}mse{c}^{-1}$
