The electric field in a particular space is E→ = ((1000.0 − 2300.0z) N/C)k^ with z in meters. Consider a cylindrical Gaussian surface of radius 12.0 cm that is coaxial with the z-axis. One end of the cylinder is at z = 0, and the other end of the cylinder is at z = 2.10 m. What is the net charge contained by the cylinder? C
