A) \[r\propto n\]
B) \[r\propto {{n}^{2}}\]
C) \[r\propto \frac{1}{n}\]
D) \[r\propto \frac{1}{{{n}^{2}}}\]
Correct Answer: B
Solution :
Key Idea: Bohr gave following formula to calculate the radius of orbit. \[{{r}_{n}}=\frac{{{n}^{2}}{{h}^{2}}}{4{{\pi }^{2}}K{{e}^{2}}{{Z}^{2}}}\] where all things except\[{{n}^{2}}\]are constant \[\therefore \] \[{{r}_{n}}\propto {{n}^{2}}\]You need to login to perform this action.
