Figure (a) shows a narrow charged solid cylinder that is coaxial with a larger charged cylindrical shell. Both are nonconducting and thin and have uniform surface charge densities on their outer surfaces. Figure (b) gives the radial component E of the electric field versus radial distance r from the common axis. The vertical axis scale is set by E, = 3.0 x 10° N/C. What is the linear charge density of the shell? 12.6 -Eg r (cm) (a) (b) Number i -5.8 Units nC/m
