Problem
In vacuum, a potential difference V is maintained between points a distance d apart. The corresponding electric field E accelerates an electron from rest to a speed v over that distance. Which one of the following statements is true?
(a) E does not depend on d; (b) E depends on V, not on d;
(c) E depends only on d; (d) v depends on V, not on d.
