Problem
Four particles, each of mass m, start from rest and are accelerated through the same potential difference of 50V. Their charges are +e, +2e, −e, and −2e, respectively. Which option correctly ranks the magnitudes of their final speeds from greatest to least?
(a) +2e>+e>−e>−2e
(b) +2e=+e=−e=−2e
(c) +2e=−2e>+e=−e
(d) +e=−e>+2e=−2e
