no options??????????
4 charges are placed each on a distance a frm origin.
-2q at +x axis
3q at +y axis
-2q at -x axis
+q at -y axis
dipole moment of configuration is ??

Net charge =zero
so dipole moment=∫qdr
and if netcharge =0 then we can measure dipole moment about any point..
considering about say +3q
+q(-2a)j+(-2q)(ai-aj)+(-2q)(-ai-aj)
=(-2aq+2qa+2qa)j
=2aqj
