HW 10 Phys5405 f07 due 11/29/07 1) For the charge densities shown in (a) and (b) of JDJ 4-1, find the dipole moment and all the quadrupole terms (ie Q xx ). For part b get the complete potential in the xy plane from Coulomb’s law. For points far from the origin compare the full potential with the approximate one up to and including the quadrupole term. 2) Use the charge density of JDJ chapter 4-7 and obtain the charge, dipole, and quadrupole moment terms (as 1b). 3) JDJ chapter 4-10. 4) In JDJ 1.6 (c) you calculated the capacitance/length of the two concentric cylinders,

Unformatted text preview: neglecting edge effects. The axis of the cylinders was the z axis. Recalculate the capacitance for the following cases: a) A dielectric with permitivity ± exists between the conductors. b) A dielectric with permitivity ± and inner radius a and outer radius c ( c > a, c < b ) lies between the conductors. c)A dielectric with permitivity ± and inner radius a and outer radius b lies between the plates in the region,-d < z < d , d << L . 1...
