Please answer b and c with clear calculation, Correct answer is
shown in fig
The figure shows the cross-section of a system comprising of a
communication co-axial cable of length l, running parallel to a
conducting wall at zero potential. The dimensions are length of the
cable l = 10 m, distance from the centre of the cable to the
conducting wall d =1cm, outer radius of the cable r2 = 5mm, inner
radius of the cable r1=1mm and permittivity of the cable dielectric
ε=2ε0 F/m. The metallic shield of the cable at radius r2 is
connected to ground.

QUESTION 2 (0) ED E The figure shows the cross-section of a system comprising of a communication co-axial cable of length 1, running parallel to a conducting wall at zero potential. The dimensions are length of the cable 1 = 10 m, distance from the centre of the cable to the conducting wall d =lcm, outer radius of the cable r2 = 5mm, inner radius of the 12 cable ri=1mm and permittivity of the cable dielectric e=2€0 F/m. The metallic shield of the cable at radius r2 is connected to ground. (a) Draw the capacitive network formation for the system. Figure 2 (b) Find the capacitance between various conductors. The capacitance between the conductor 2 and the ground plane, C20 should be calculated using the ‘Method of Image'. i.e., C20=2C TEO where, C= F/m and, D=2d 2 D D In 20- 2r2 2r2 Ans: C12 = 0.691 nF, C20= 0.422 nF, C10 =0 (c) Find the capacitance matrix for this system. Ans: [0.691 -0.691; -0.691 1.113] nF
