A point charge is located at the center of a thin spherical conducting shell of inner and outer radii r₁ and r₂, respectively. A second thin spherical conducting shell of inner and outer radii R₁ and R₂, respectively, is concentric with the first shell. The flux is as follows for the different regions of this arrangement. -13.8 x 10³ Nm²/C for r R₂ point charge inner shell outer shell 0 Determine the magnitude and sign of the point charge and the charge on the surface of the two shells. με UC μC

The figure is a section of a conducting rod of radius R₁ = 1.50 mm and length L = 12.10 m inside a thin-walled coaxial conducting cylindrical shell of radius R₂ = 11.8R₁ and the (same) length L. The net charge on the rod is Q₁ = +3.62 × 10-12 C; that on the shell is Q2 = -2.0501. What are the (a) magnitude E and (b) direction (radially inward or outward) of the electric field at radial distance r = 2.13R₂? What are (c) E and (d) the direction at r = 5.12R₁? What is the charge on the (e) interior and (f) exterior surface of the shell? R₂ R₁
