Consider a region inside which, there are various types of charges but the total charge is zero. At points outside the region.
1
the electric field is necessarily zero.
2
the electrie fieid is due to the dipole moment of the charge distribution only.
3
the dominant electric field is inversely proportional to r3, for large r (distance from the origin).
4
the work done to move a charged particle along a closed path, away from the region will not be zero.
