A Nonuniform Electric Field Is Directed Along the X-Axis at All

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 6000 N/C and 1000 N/C respectively, and are directed as shown. What is the net electric flux passing through the cylindrical surface?

A) -160 N ∙ m²/C
B) -350 N ∙ m²/C
C) 0.00 N ∙ m²/C
D) +350 N ∙ m²/C
E) +160 N ∙ m²/C
