A) \[6.64\text{ }\overset{\text{o}}{\mathop{\text{A}}}\,\]
B) \[~1.058\text{ }\overset{\text{o}}{\mathop{\text{A}}}\,\]
C) \[2.116\text{ }\overset{\text{o}}{\mathop{\text{A}}}\,\]
D) \[~13,28\text{ }\overset{\text{o}}{\mathop{\text{A}}}\,\]
Correct Answer: A
Solution :
\[mvr=n\frac{h}{2\pi }=2\left( \frac{h}{2\pi } \right)\]or \[mvr=\frac{h}{\pi }\] \[\therefore \]\[\frac{h}{mv}=de-\]Broglie wavelength \[=\pi r\] \[=(3.14)(2.116\overset{\text{o}}{\mathop{A}}\,)=6.64\overset{\text{o}}{\mathop{A}}\,\] Hence, the correction option is [a].You need to login to perform this action.
