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
