Chapter 6: Problem 10
A coaxial cable has conductor dimensions of \(a=1.0 \mathrm{~mm}\) and \(b=2.7 \mathrm{~mm}\). The inner conductor is supported by dielectric spacers \(\left(\epsilon_{r}=5\right)\) in the form of washers with a hole radius of \(1 \mathrm{~mm}\) and an outer radius of \(2.7 \mathrm{~mm}\), and with a thickness of \(3.0 \mathrm{~mm}\). The spacers are located every \(2 \mathrm{~cm}\) down the cable. ( \(a\) ) By what factor do the spacers increase the capacitance per unit length? \((b)\) If \(100 \mathrm{~V}\) is maintained across the cable, find \(\mathbf{E}\) at all points.
