MCQ
According to Bohr’s principle, the relation between principle quantum number $(n)$ and radius of orbit is
- A$r \propto n$
- ✓$r \propto {n^2}$
- C$r \propto \frac{1}{n}$
- D$r \propto \frac{1}{{{n^2}}}$
✓
Answer
Correct option: B.
$r \propto {n^2}$
b
(b) Bohr suggest a formulae to calculate the radius and energy of each orbit and gave the following formulae
(b) Bohr suggest a formulae to calculate the radius and energy of each orbit and gave the following formulae
${r_n} = \frac{{{n^2}{h^2}}}{{4{\pi ^2}km{e^4}Z}}$
Where except ${n^2}$, all other unit are constant so ${r_n} \propto {n^2}$.
