A) 100 eV
B) 14375 eV
C) 12000 eV
D) 12375 eV
Correct Answer: D
Solution :
Energy of bombarding electron is \[E=\frac{hc}{\lambda }=\frac{6.6\times {{10}^{-34}}\times 3\times {{10}^{8}}}{1\times {{10}^{-10}}}\] \[=19.8\times {{10}^{-16}}J\] \[E=\frac{19.8\times {{10}^{-16}}}{1.6\times {{10}^{-19}}}eV\] \[=12375eV\]You need to login to perform this action.
