1. The problem statement, all variables and given/known data consider a long cylindrical dielectric shell of inner cross-sectional radius a , outer radius b, and constant volume charge density raw zero . THe potenials of the ineer and outer surfaces of the cylindrical shell are held at potentials 0 and V respectively as shown in the adjacent figure. Solve the appropriate boundary value problem and use the given boundary conditions to find the electric potential at any point inside the shell 2. Relevant equations 3. The attempt at a solution i used poissons equation between a and b is that true or should i also do laplaces equation inside a please reply??
