    Energy Density of a Charged Sphere?

    yes it does... so it looks like i assumed that because the charge is constant, that the electric field is constant, which is not the case. I missed 2 big equations in that, so looks like I am not even going to get that much partial credit :frown: at least now i can sleep knowing the...

    Energy Density of a Charged Sphere?

    Homework Statement Since this was on the test, I won't be able to type out the question verbatim, but here it goes: You have a plastic sphere with charge equally distributed through out the sphere. The radius of the sphere is a. The energy stored in the total sphere is E0 (not to be...
