A long thin plastic rod of length L 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. R₂ R₁ Determine the net electric field at a distance r < R₁ from the center (in the empty space between the rod and the cylindrical shell). Make sure to state both the magnitude and the direction of the field. Determine the net electric field at a distance r > R₂ from the center (outside of the cylindrical shell). Make sure to state both the magnitude and the direction of the field. Determine the net electric field É at a distance R₁ < r < R₂ from the center (inside the body of the cylindrical shell). Make sure to state both the magnitude and the direction of the field.
