I'm reposting this thread with some editing suggested by fresh_42:
1. Homework Statement
Calculate the mass, velocity and the de Broglie wavelength of an electron and an alpha particle, given the kinetic energy K = 2MeV
please find attached![/B]
I went through my calculations again and I think I have one problem in determining the formula of relativistic kinetic energy. What I used is: E = m*c^2, where m - the effective mass of the electron. I'm afraid I should've used
E = m*c^2 - m0*c^2, where m = m0/sqrt(1-β^2). Is that correct?
