Hello Sourabh,
Consider an equilateral triangle of side a. Point A and B have charges +q where A has -2q charge. The system as two dipoles with p1 and p2 along BA and CA respectively.
The angle between the dipole moment is 60 degree.
The resultant dipole moment(P): root(P^2+P^2+2PCos60*) = root(3P)
where P = qa.
Dipole Moment, P = root(3qa)
