Electric potential on dipole axis varies inversely as ……….. Of distance of point from the center of electric dipole.

At a point on the axis of an electric dipole

Field intensity due to a single charge varies inversely as ……….. of distance and field intensity due to an electric dipole varies inversely as ………. of distance of the point.

Electric field intensity (E) due to an electric dipole varies with distance (r) of the point from the center of dipole as :

(a) Obtain the expression for the potential due to a point charge. (b) Use the above expression to show that the potential, due to an electric dipole (length 2a), varies as the inverse square' of the distance r of the 'field point' from the centre of the dipole for rgta .

The electric potential at a point on the axis of an electric dipole depends on the distance r of the point from the dipole as

The magnitude of electric field intensity at a point on the axis of short dipole is 30V/m. The distance of the point from the centre of the dipole is 2m. Then potential at that point is

The electric field of an electric dipole at a point on its axis , at a distance d from the center of the dipole, varies as
