List-I shows four configurations, each consisting of a pair of ideal electric dipoles. Each dipole has a dipole moment of magnitude p, oriented as marked by arrows in the figures. In all the configurations the dipoles are fixed such that they are at a distance 2 r apart along the x direction. The midpoint of the line joining the two dipoles is X.

Correct Answer is : P⟶2,Q⟶1,R⟶4,S⟶5

{\P} \rightarrow 3, {\Q} \rightarrow 1, {\R} \rightarrow 2, {\S} \rightarrow 4

{\P} \rightarrow 4, {\Q} \rightarrow 5, {\R} \rightarrow 3, {\S} \rightarrow 1

{\P} \rightarrow 2, {\Q} \rightarrow 1, {\R} \rightarrow 4, {\S} \rightarrow 5

{\P} \rightarrow 2, {\Q} \rightarrow 1, {\R} \rightarrow 3, {\S} \rightarrow 5
