Question

The velocity of
an electron with de-Broglie
wavelength of 1.0
x10 nm is​

Answer 1

Answer: Velocity is 72739m/s.

Explanation:

• Formula of De-Broglie wavelength is Ф=h/mv.
• Given that Ф=10nm and we know that mass of electron is m=9.11×10^-31 kg.
• v=h/Фm
• v=(6.63×10^-34)/(10×10^-9×9.11×10^-31)
• v=72739m/s
