Gauss's law: A nonuniform electric field is directed along the x-axis at all points in space. This magnitude of the field varies with x, but not with respect to y or z. The axis of a cylindrical surface, 0.80 m long and 0.20 m in diameter, is aligned parallel to the x-axis, as shown in the figure. The electric fields E1 and E2, at the ends of the cylindrical surface, have magnitudes of
and
respectively, and are directed as shown. (ε0 = 8.85 × 10-12 C2/N ∙ m2) The charge enclosed by the cylindrical surface is closest to 
A) -1.1 nC.
B) 1.1 nC.
C) -2.4 nC.
D) -4.8 nC.
E) 4.8 nC.
