SATHEE: Atoms And Nuclei Question 103

Atoms And Nuclei Question 103

Question: Orbital acceleration of electron is [RPET 2001]

Options:

A) $\frac{n^{2} h^{2}}{4 π^{2} m^{2} r^{3}}$

B) $\frac{n^{2} h^{2}}{2 n^{2} r^{3}}$

C) $\frac{4 n^{2} h^{2}}{π^{2} m^{2} r^{3}}$

D) $\frac{4 n^{2} h^{2}}{4 π^{2} m^{2} r^{3}}$

Show Answer

Answer:

Correct Answer: A

Solution:

$m v r = \frac{n h}{2 π}$
Þ $v = \frac{n h}{2 π m r}$
Þ $\frac{v^{2}}{r} = \frac{n^{2} h^{2}}{4 π^{2} m^{2} r^{3}}$ .
