1. The problem statement, all variables and given/known data Let me just put this here: http://i.imgur.com/dgcWAC3.png . 2. Relevant equations E_flux=EA=(q_encl)/(permittivity) Area=4pir^2 3. The attempt at a solution Whenever I manipulate the above equations, I get a term of the form R/r, which implies, R being 5 cm, and r being the radius inside. This implies that the field goes to infinity at the center, when I'm pretty sure by spherical symmetry it is 0!
