A) \[0.5\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
B) \[1.7\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
C) \[2.4\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
D) \[1.2\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
Correct Answer: B
Solution :
momentum \[P=\sqrt{2mE}\] and \[E=eV\] \[\lambda =\frac{h}{p}=\frac{h}{\sqrt{2mE}}\] \[=\frac{6.6\times {{10}^{-34}}}{\sqrt{2\times 9.1\times {{10}^{-31}}\times 1.6\times {{10}^{-19}}\times 50}}\] \[=1.7\times {{10}^{-10}}M\] \[=1.7\,\overset{\text{o}}{\mathop{\text{A}}}\,\]You need to login to perform this action.
