Problem
An electron (−e, mass me), a proton (+e, mass mp), and an alpha particle (+2e, mass 4mp) are each released from rest and accelerate through the same potential difference of 600V, gaining kinetic energy from the electric field. Rank the magnitudes of their final speeds from largest to smallest and briefly justify your ranking.
