Question

The angular speed of the electron in the nth orbit of Bohr’s hydrogen atom is:

• A. Directly proportional to n
• B. Inversely proportional to $\sqrt{n}$
• C. Inversely proportional to $n^2$
• D. Inversely proportional to $n^3$

Answer 1

The correct option is D

Inversely proportional to $n^3$

$\omega =\frac{v}{r}$
Further, $v\propto \frac{1}{n}$ and $r\propto n^2$
