Vedclass · Answer

(B) According to Bohr's theory of the hydrogen atom,the velocity $(v_n)$ of an electron in the $n^{	ext{th}}$ orbit is given by the formula:$v_n = \frac{2 \pi k Z e^2}{n h}$Where:$k$ is Coulomb's constant,$Z$ is the atomic number (for hydrogen,$Z=1$),$e$ is the charge of the electron,$h$ is Planck's constant,$n$ is the principal quantum number (orbit number).Since $2, \pi, k, Z, e^2,$ and $h$ are constants,the velocity is inversely proportional to the orbit number $n$.Therefore,$v_n \propto \frac{1}{n}$.

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