Using the de **Broglie wavelength **relation p = h/ and the fact that the magnitude of the momentum is related to the kinetic energy by p = (2mK)1/2, we have. h/p = h/(2mK)1/2. Applying this result to the electron and the proton gives. e/ p = (2mpK)1/2/(2meK)1/2. = (mp/me)1/2 = (1.67kg/9.11kg)1/2 = 42.8.
