A) \[4.16\times {{10}^{-34}}\,J\text{-}s\]
B) \[3.32\times {{10}^{-34}}\,J\text{-}s\]
C) \[1.05\times {{10}^{-34}}\,J\text{-}s\]
D) \[2.08\times {{10}^{-34}}\,J\text{-}s\]
Correct Answer: C
Solution :
| [c] Change in the angular momentum |
| \[\Delta L={{L}_{2}}-{{L}_{1}}=\frac{{{n}_{2}}h}{2\pi }-\frac{{{n}_{1}}h}{2\pi }\]\[\Rightarrow \Delta L=\frac{h}{2\pi }({{n}_{2}}-{{n}_{1}})\] |
| \[=\frac{6.6\times {{10}^{-34}}}{2\times 3.14}(5-4)\]\[=1.05\times {{10}^{-34}}J\text{-}S\] |
