A long cylindrical insulating shell has an inner radius of a=1.43 m and an outer radius of b=1.67 m. The shell has a constant charge density of 7×10-9 C/m3. The picture shows an end-on cross-section of the cylindrical shell. a) What is the magnitude of the electric field (Eout) at a distance of r=1.91 m from the axis? b) What is the magnitude of the electric field (Ein) at a distance of r=1.55 m from the axis? c) If we take the potential at the axis to be zero, what is the electric potential (Vb) at the outer radius of the shell?
