I have a question that involves two electric dipoles that are situated at the origin and are perpendicular to each other. Other than that they are identical in every way. Each one oscillates so at cos (w(t-r/c)). I'm asked which multipole moments oscillate. Wouldn't it just be the dipole moment and nothing else. Or would a quadrupole moment work. I can find the E and B fields through superposition and the radiated power, but all of my fields are still 1/r dependent. What am I doing wrong?
