    Finding the energy density outside of an isolated charged sphere

    Alright, I've modified my formula to take into account the radius outside the sphere. by replacing placeholder R with ##\frac V {{\frac d 2} + r}## where "r" is the radius approaching infinity. plugging that back into the density equation, I eventually get this $$u = \frac {2 \epsilon_0 V^2}...

    Finding the energy density outside of an isolated charged sphere

    Homework Statement A charged isolated metal sphere of diameter d has a potential V relative to V = 0 at infinity. Calculate the energy density in the electric field near the surface of the sphere. State your answer in terms of the given variables, using ε0 if necessary.Homework Equations Since...
