Question

10. Suppose you have a spherical shell made of copper with inner radius R? = 20 cm, outer radius R? = 22 cm, and total charge +25.0 µC. The region between R? and R? is a solid shell of copper, and the region for r < R? is empty space. a. What is the Electric Field for R? < r < R?? (inside the solid shell) Explain. b. What is the Electric Field for r < R?? (in the inner cavity) Explain. c. What is the Electric Field at a distance of 30cm from the center of the spheres? (give numerical magnitude and direction) (show all your work!) d. What is the Electric Potential at a distance of 30cm from the center of the spheres? (give actual numerical value) (show all your work!) e. What is the Electric Potential at r = R?? (show all your work!) f. What is the Electric Potential at r < R?? g. Where are the charges located? Be specific. h. What is Electric Flux through a spherical surface with radius 100cm concentric with the spheres? (give actual numerical value) (show all your work!)
