An electron is accelerated through a potential difference of \( 10,000 \mathrm{~V} \). Its de Broglie wavelength is, (nearly): \( \left(\mathrm{m}_{\mathrm{e}}=9 \times 10^{-31}\right. \) \( \mathrm{kg}) \)
\( (2019) \)
a. \( 12.2 \times 10^{-13} \mathrm{~m} \)
๒. \( 12.2 \times 10^{-12} \mathrm{~m} \)
c. \( 12.2 \times 10^{-14} \mathrm{~m} \)
d. \( 12.2 \mathrm{~nm} \)
