*33. If a weak electric field of magnitude E is applied to an atom in its ground state (Stark effect), what happens to the energy of the atom?
(A)It is changed by an amount proportional to E.
(B)It is changed by an amount proportional to E2.
(C)It is changed by an amount proportional to E3.
(D)It is changed by an amount proportional to E4.
(E)It is not changed.
