A) \[6.3\,\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
B) \[3.8\,\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
C) \[24.6\,\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
D) \[0.12\,\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
Correct Answer: B
Solution :
de-Broglie's wavelength associated with a charged particle, \[\lambda =\frac{h}{\sqrt{2mKE}}\] \[=\frac{6.6\times {{10}^{-34}}}{\sqrt{2\times 9.1\times {{10}^{-31}}\times 10\times 1.6\times {{10}^{-19}}}}\]\[=3.8\overset{\text{o}}{\mathop{\text{A}}}\,\]You need to login to perform this action.
