Atomic Physics Question 10

Question 10 - 2024 (30 Jan Shift 2)

An electron revolving in $n^{\text {th }}$ Bohr orbit has magnetic moment $\mu _n$. If $\mu _n \alpha n^{x}$, the value of $x$ is:

(1) 2

(2) 1

(3) 3

(4) 0

Show Answer

Answer: (2)

Solution:

Magnetic moment $=i \pi r^{2}$

$\mu=\frac{\text { evr }}{2}$

$\mu \alpha\left(\frac{1}{n}\right) n^{2}$

$\mu \alpha n$

$x=1$
