This was a recent problem on an exam that I did poorly on that I was wondering if I could acquire some assistance to further my understanding.
A long plastic pipe has an inner radius A and an outer radius B. Charge is uniformly distributed over the volume A<r<B, and the amount of charge is ρ C/m^3. Find the potential difference between r=B and r=0.
∫ E dA = q enc / ε
I'm stumped on how to carry out this problem, but I'm thinking that using Gauss's Law to find the electric field would be helpful so that you can then integrate it to find V. However, my cylindrical integration skills are a little shaky and I'm not sure if this is the the correct way. Any help would be appreciated. Thanks
