How the linear velocity $v$ of an electron in the Bohr orbit is related to its quantum number $m$

Options:

Answer:

Solution:

$∵$ Linear velocity of an electron in a orbit of H like atom,
$v = 218 \times 1 0^{6} \times \frac{Z}{n} m / s = \frac{c _{0}}{137} \cdot \frac{Z}{n}$
where, $Z =$ number of protons in nucleus, $n =$ principal quantum number and $c_{o} =$ speed of light in free space, Thus, we have
$v \propto \frac{1}{n}$
