A) 2 : 1
B) 4 : 1
C) 3 : 1
D) 5 : 1
Correct Answer: B
Solution :
According to Bohr's rule \[r\propto {{n}^{2}}\] where r = radii of orbit n = number of orbit. \[\therefore \] \[\frac{{{r}_{1}}}{{{r}_{2}}}=\frac{n_{2}^{2}}{n_{1}^{2}}=\frac{{{(2)}^{2}}}{{{(1)}^{2}}}=\frac{4}{1}\] \[\therefore \]Ratio of second and first orbit of H is 4:1You need to login to perform this action.
