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. The electric fields e1 and e2, at the ends of the cylindrical surface, have magnitudes of 6000 n/c and 1000 n/c respectively. Required:
What is the net electric flux passing through the cylindrical surface?
