Conceptual question 2-23 Q2-23] Coaxial cable with a radial variation of permittivity. A coaxial cable is filled with a continuously in- homogeneous dielectric and connected to voltage source. The permittivity of the dielectric is a function of the radial distance r from the cables axis and no other coordinates. Consider vectors D and E in the cable. The way in which each of the vector varies throughout the dielectric is the same as in the same cable if air-filled for (A) both vectors. ) vector D only. (C) vector E only. (D) None of the vectors I Conceptual question 2-24 [Q2-24] Coaxial cable with four dielectric sectors. Repeat the previous equation but for a coaxial cable with a dielectric in the form of four 90 sectors with different permittivities, the cross section of which is shown in Fig. Q2.10 r4 rl 9090 90 r2 r3 coaxial cable Figure Q2.10 Cross section of a coaxial cable with a four-piece dielectric; for Question 2.24 Conceptual question 2-23 Q2-23] Coaxial cable with a radial variation of permittivity.
