A) \[0.66\,\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
B) \[9.38\,\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
C) \[0.246\,\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
D) \[0.123\,\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
Correct Answer: D
Solution :
Here: Potential difference\[V=100kV\] \[=100\times {{10}^{3}}V\] The minimum wavelength of the \[X-\]rays is \[{{\lambda }_{\min }}=\frac{hc}{eV}=\frac{6.6\times {{10}^{-34}}\times 3\times {{10}^{8}}}{1.6\times {{10}^{-19}}\times 100\times {{10}^{3}}}\] \[=0.123\times {{10}^{-10}}\] \[=0.123\overset{\text{o}}{\mathop{\text{A}}}\,\]
