A coaxial capacitor structure is illustrated in the schematic diagram of Figure Q.2. The capacitor has a length of L. The radius of the inner and outer conductors of the capacitor are a and ß respectively. The gap between the two conductors is filled with a homogeneous charge-free dielectric material with electrical permittivity ɛ. While the outer conductor is grounded, the inner conductor is kept at a constant potential of Vo. Given that L = 5 mm, a = 1 mm, and ß = 3 mm.
