Homework Statement
Show that, if a charge distribution has cylindrical symmetry, then knowing the value
of Qzz allows you to determine the entire quadrupole moment matrix.
Homework Equations
Tr Q=0, ie Qxx+Qyy+Qzz=0
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.
