A positive line charge with line charge density + is at the center of a thick conducting cylindrical shell that has line charge density -2/3. The conducting cylindrical shell has inner radius r and outer radius 72. Consider three points of interest A, B, and C, at radii from the center TA, TB, and TC. As shown in the figure, 0 < < < 12. Metal cylinder -2/3 5. Determine A1 and A2, the induced surface charge densities on the inner and outer surfaces of the conducting shell, respectively. 6. Assuming that =+2 C/m, r =0.15 m, and r2 =0.20 m, calculate the electric field at position C, a distance Tc=0.25 m from the center.
