Expert Answer
Dear student
The mass of electron is less than that of proton, hence the de-broglie wavelength[ λ=h/(2mk)1/2 ]of electron will be greater than that of proton.
The mass of electron is less than that of proton, hence its momentum (mv) will be less than that of proton.
Hope this clarifies your doubt.
