Aproton, a deuteron (a hydrogen nucleus containing one proton and one neutron), and an alpha particle (a helium nucleus consisting of two protons and two neutrons) initially at rest are all accelerated through the same distance in the uniform electric field created by a very large charged plate. compare their final (a) kinetic energies, (b) momentum magnitudes, (c) speeds, and (d) time intervals needed to cover the distance. (e) how do the changes in electric potential energy compare?
