34. Three concentric conducting spherical shells have inner and outer radii of 0.1, 0.2, 0.3, 0.4, 0.5, 0.6 meters. The inner shell has a net charge of -1C, the middle shell has a net charge of -2C, and the outer shell has a net charge of -3C. There are no other charges in the system and all charges remain at rest. What is the surface charge density on the inner surface of the largest shell? a) 0 C/m b) +0.45 C/m c) -0.45 C/m d) +0.95 C/m e) -0.95 C/m
