A nоnunifоrm electric field is directed аlоng the x-аxis. The mаgnitude of the field varies with x, but not with respect to y or z. The axis of a closed cylinder, 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 closed cylinder? Choose the best answer below.
