In electrostatics both the electric field intensity (E) and potential (V) are closely related. Show that the line integral of electric field along any closed path is zero.

E is the electric field intensity at any point in a uniform electric field. : What is meant by uniform electric field?

The figure shows some of the electric field lines corresponding to an electric field. If E is the intensity of electric field and V is the potential

The direction of electric field intensity at a point on the equatorial line of an electric dipole of dipole moment is

An electric dipole is placed in a uniform electric field of Intensity E as shown in the figure. If the dipole is placed in a nonuniform electric field what nature of motion does it show?
