Answer:
The speed of an electron is 0.01908 m/s.
Explanation:
De-Broglie wavelength is given by:
[tex]\lambda=\frac{h}{mv}[/tex]
where, [tex]\lambda[/tex] = wavelength of a particle
h = Planck's constant = [tex]6.626\times 10^{-34}Js[/tex]
m = mass of particle
v = velocity of the particle
Velocity of an electron = v
Mass of an electron = [tex]9.1\times 10^{-31}kg[/tex]
Wavelength of electron is twice the displacement in seconds which is velocity of an electron.
Then.wavelength of an electron = [tex]\lambda =2v[/tex]
[tex]\lambda =2v=\frac{6.626\times 10^{-34}Js}{9.1\times 10^{-31}kg\times v}[/tex]
v = 0.01908 m/s
The speed of an electron is 0.01908 m/s.
