Two point charges \[+q\] and \[-q\] are held fixed at \[(-d,\,0)\] and \[(d,\,0)\] respectively of a \[(X,\,Y)\] coordinate system. Then [IIT 1995]

The electric field \[\overrightarrow{E}\] at all points on the \[X-\]axis has the same direction

E at all points on the \[Y-\]axis is along \[\hat{i}\]

Dipole moment is \[2qd\] directed along \[\hat{i}\]

Work has to be done in bringing a test charge from infinity to the origin
