(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Show that, if a charge distribution has cylindrical symmetry, then knowing the value

of Qzz allows you to determine the entire quadrupole moment matrix.

2. Relevant equations

Tr Q=0, ie Qxx+Qyy+Qzz=0

3. The attempt at a solution

Because of the cylindrical symmetry, the charge density changes as a function of ρ, where ρ=(x^2+y^2)^1/2. Then I don't really know where to go from there.
