A) n = 4
B) n = 2
C) n = 16
D) n = 3
Correct Answer: B
Solution :
\[r\propto {{n}^{2}}\ i.e.\frac{{{r}_{f}}}{{{r}_{i}}}={{\left( \frac{{{n}_{f}}}{{{n}_{i}}} \right)}^{2}}\] Þ \[\frac{21.2\times {{10}^{-11}}}{5.3\times {{10}^{-11}}}={{\left( \frac{n}{1} \right)}^{2}}\] Þ \[{{n}^{2}}=4\] Þ n = 2You need to login to perform this action.
