hey for those interested I actually sorted myself out on this one, the final equation i used was the integral of rho(r^2 -a^2)*dr / 2 *r* e0 [a,R]. Where rho is the charge density, a is the interior radius, r is a variable, dr is the differential radius element, and e0 is epsilon naught, 8.854e-12.

Homework Statement A long cylindrical insulating shell has an inner radius of a = 1.37 m and an outer radius of b = 1.60 m. The shell has a constant charge density of 2.70 10−9 C/m3. The picture shows an end-on cross-section of the cylindrical shell. What is the magnitude of the electric...
