Find the momentum, kinetic energy, and total energy of an electron moving at a speed of c / ε The rest energy of an electron is 0.51099893 MeV/c^2
Compute the de Broglie wavelengths of (a) an electron, (b) a proton, and (c) a Au nucleus (A=197 g/mole) with a kinetic energy of 20 eV, and these same particles (parts d, e, & f) if they have a kinetic energy of 10 GeV. (Relativity is important f..
