A metallic sphere with a radius of 1.5 m and a charge of 19 µC is placed withing a metallic shell with an inner radius of 4.35 m and an outer radius of 5.15 m. We measure an electric field of 3600 N/C pointing towards the shell at 7.05 m of its center. What's the net charge of the shell? The shell's area charge density on the outside? The charge of the inner shell? And what's the electric field at 2.05 m of the center? .
