A) \[1.22\text{ }\overset{{}^\circ }{\mathop{A}}\,\]
B) \[1.75\text{ }\overset{{}^\circ }{\mathop{A}}\,\]
C) \[2\text{ }\overset{{}^\circ }{\mathop{A}}\,\]
D) None of these
Correct Answer: A
Solution :
Energy of the electron, when it comes out from the second plate = 200 eV - 100 eV = 100 eV Hence accelerating potential difference = 100 V \[{{\lambda }_{Electron}}\,\,=\,\,\frac{12.27}{\sqrt{V}}\,=\,\frac{12.27}{\sqrt{100}}\,\,=\,1.23\,\,\overset{{}^\circ }{\mathop{A}}\,\]You need to login to perform this action.
