An electric field is E=(200 N/C) i in the region x>0 and E=( - 200 N/C) i in the region x<0. An imaginary soup-can shaped surface of length 20 cm and radius R=5.0 cm has its center at the origin and its axis along the x axis, so that one end is at x= +10 cm and the other is x= -10 cm.
a) What is the net outward flux through the entire closed surface?
b) What is the net charge inside the closed surface?
