Great, thanks for your help guys, appreciate it.

Hi TSny Ok, I have \frac{k}{\epsilon_{0}r^2} as a solution to the associated DE. To get this I used ∇E=0 then substituted my particular solution for E. Do I then just state that at the boundary, E=0 and then build an equation from my two E(r) equations which satisfies this condition? I'm just...

Homework Statement A hollow spherical shell carries charge density \rho=\frac{k}{r^2} in the region a<=r<=b, where a is the inner radius and b is the outer radius. Find the electric field in the region a<r<b. I'm not allowed to use integral form of Gauss's law, must use differential...

usyd student? if so try lecture 7 slide 12 ;) I'm not sure about solving the fluid equation for p=0 - apparently its a seperable integral or something, but i think you can use what's provided on slides without proof. From there I think you are just trying to draw a relationship between the flat...
