A rod AB of length L and mass m is uniformly charged with a charge Q, and it is suspended from end A as shown in fig. The rod can freely rotate about A in the plane of the figure. An electric field E is suddenly switched on in the horizontal direction due to which the rod gets turned by a maximum angle of 90∘. The magnitude of E is equal of n Mg/Q. Find the value of n.

In each situation of Column-I two electric dipoles having moments p 1 and p 1 of same magnitude (that is ,p1=p2) are placed on x-axis symmetrically about origin in different orientations as shown. In column-II certain inferences are drawn for these two dipoles. Then match the different orientations of dipole in column-I with the corresponding result in column-II.
