Chapter 6: Problem 9
Two coaxial conducting cylinders of radius \(2 \mathrm{~cm}\) and \(4 \mathrm{~cm}\) have a length of \(1 \mathrm{~m}\). The region between the cylinders contains a layer of dielectric from \(\rho=c\) to \(\rho=d\) with \(\epsilon_{r}=4\). Find the capacitance if \((\) a) \(c=2 \mathrm{~cm}, d=3 \mathrm{~cm} ;\) (b) \(d=4 \mathrm{~cm}\), and the volume of the dielectric is the same as in part \((a)\).
