Unformatted text preview: from above, a counter clockwise current I. What is B at (5a/2,a/2)? 4a) For a pure electric dipole, show that the quadrupole term vanishes. 4b) For the charge densities shown in (a) and (b) of JDJ 41, nd the dipole and quadrupole moment. For part (b) get the complete potential in the xy plane from Coulombs law. For points far from the origin compare the full potential with the approximate one up to and including the quadrupole term. 5) JDJ chapter 410. 1...
