The figure (Fig. 1) shows a long cylindrical capacitor consists of a solid conducting core with radius r1=7mm and outer hollow conducting tube with an inner radius of r2=29mm . The length of the capacitor is L=32cm . Figure 2 is the cross sectional view of the system. This system of rod and shell is connected to a voltage source of emf E=6.4volts . There is no dielectric material present in the system as of now. Fig.2 PartIa) Calculate the capacitance of this capacitor.capacitanceGive your answer up to at least three significance digits.Fb) Say the inner rod is negativelycharged. Given this, calculate the charge density of the outer surface. And show how the electricfield lines are oriented in this system. Hint: you can use the cross section for this (Fig. 2).charge density of the outer surfaceGive your answer up to at least three significance digits.C/m2

Given, The radius of solid conducting core, r1=7mm The hollow conducting tube with an inner radius,…
