Suppose you released a single proton from rest at some point X in an electric field, and that you then released a single electron from rest at the same point X. How would the motions of the proton and electron compare, just after their release from rest?
A) They would move in opposite directions, and the electron would move fastest.
B) They would move in opposite directions, and the proton would move fastest.
C) They would move in the same directions, and the electron would move fastest.
D) They would move in opposite directions, and at the same speeds.
E) They would move in the same directions, and the proton would move fastest.
