A long thin plastic rod of length _ and with uniform charge @ is located in the center of a thick plastic cylindrical shell. The shell has uniform charge -Q, length L. inner radius R1, and outer radius R2. The space between the rod and the inner radius of the shell is empty. R1/ Q4.1 Gauss 5 Points Determine the net electric field E at a distance r Ry from the center (outside of the cylindrical shell). Make sure to state both the magnitude and the direction of the field.
