Q156 / 160 · AP EAMCET 2023 (18 May Shift 1) · Physics
If ' $\mu$ ' is the magnetic moment of an electron revolving around hydrogen nucleus in an orbit of principal quantum number ' $n$ ', then
- A$\mu \alpha n^2$
- Correct answerB$\mu \alpha \mathrm{n}$
- C$\mu \alpha \frac{1}{n}$
- D$\mu \alpha \frac{1}{\mathrm{n}^2}$
Solution
Magnetic moment is given as
$\mu=-\frac{\mathrm{neh}}{2 \mathrm{~m}}$
Here, $\mathrm{n}=$ principle quantum number $\mu \propto \mathrm{n}$
Hence, the correct answer is option: 'B'.
