If an electron and proton have the same de broglie wavelength which particle have greater speed

Question

sonika p · Answer

de Broglie wavelength lambda = h/mv for proton, lambda(p) = h/(mp)(vp) where, mp,vp is mass,velocity of proton, for proton, lambda(e) = h/(me)(ve) where, me,ve is mass,velocity of electron, now when wavelengths are same, velocity is inversely proportional to masses Thus, ve>vp since, me thus electron will have grater speed than proton.
