1. The problem statement, all variables and given/known data A cylindrical distribution of charge ρ = α/sqrt(r) where α = 2 µC/m^(5/2) extends from 0 cm to 9.3 cm (has radius 9.3 cm). Concentric with this is a dielectric shell with k = 5.44 of inner radius 16.6 cm and outer radius 24.9 cm. What is the electric field at 3.53 cm, 12.6 cm, 21.4 cm, and 33 cm? Answer in units of V/m. What is the surface charge density on the inner surface of the dielectric? 2. Relevant equations p = α/sqrt(r) E dA = Integral( q(enclosed)/Eps ) 3. The attempt at a solution I already got the Electric Field at 3.53 cm by integrating through the square root of the radius and multiplying by the charge density (to get 28293 V/m), but at these other points you have to account for the dielectric and I don't know how to treat the cylindrical charge distribution outside the cylinder... anyone have pointers?
