A) \[1.2\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
B) \[10.5\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
C) \[100\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
D) \[1000\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
Correct Answer: A
Solution :
Potential difference = 100 V \[\lambda =\frac{h}{\sqrt{2q\,vm}}\] \[=\frac{6.6\times {{10}^{-34}}}{2\times (1.6\times {{19}^{-19}})\times 100\times 9.1\times {{10}^{-31}}}\] \[=1.2\times {{10}^{-10}}m\] \[=1.2\,\,\overset{\text{o}}{\mathop{\text{A}}}\,\]0You need to login to perform this action.
