11. Two large parallel conducting plates are separated by a distance d, placed in a vacuum, and connected to a source of potential difference V. A "doubly charged" oxygen ion starts from rest on the surface of one plate and accelerates to the other. If e denotes the electron charge, the final kinetic energy of this ion is:
(A) 2 eV
(B) eV/d
(C) eVd
(D) Vd/e
(E) eV/2.
