Question

The angular momentum of an electron in a hydrogen atom is proportional to

• A. $1/\sqrt{r}$
• B. $1/r$
• C. $\sqrt{r}$
• D. $r^2$

Answer 1

The correct option is C $\sqrt{r}$

Angular momentum $=\frac{nh}{2\pi }$ i.e., directly proportional to $n$
Using above relation, $L$ is directly proportional to $\sqrt{r}$.
