0It is desired to obtain
a diffraction pattern for electrons using a diffraction grating with lines separated by \( 10 \mathrm{~nm} \). The mass of an electron is \( 9.11 \times 10^{-31} \mathrm{~kg} \)
What is the approximate kinetic energy of electrons that would be diffracted by such a grating?
(A) \( 1.5 \times 10^{-6} \mathrm{eV} \)
(B) \( 1.5 \times 10^{-2} \mathrm{eV} \)
(C) \( 1.5 \times 10^{-4} \mathrm{eV} \)
(D) \( 1.5 \times 10^{2} \mathrm{eV} \)
