Two concentric spheres of radii 1.65 cm and 19.0 cm, respectively, are given equal but opposite charges of 6.35e-08 C. How much energy is stored in the system (in J)?
I know V = U/q where U would be the entire energy stored in the system beacuse it's not in motion. I know q's but I just don't know how to apply it.
I've thought about this so much. I tried setting up a ridiculous integral for solving this but it just went way over my head. The question doesn't really even make sense because wouldn't some of the charges overlap each other? I think the teacher meant hollow spheres. A little point in the right direction, please. (Test tomorrow) :)
