what is the direction of field intensity at a point (i) on axail line of dipole and (ii) equatorial line of diople ?

Explanation

For a point on the axial line of dipole, the direction of electric field intensity `vec(E)` is along a line parallel to the axis of dipole directed along
the direction fo dipole moment `vec(P).`
For a point on the equatorial line of dipole,
the direction of electric, field `vec(E)` is along a line parallel to the axis of dipole directed opposite to the direction of dipole moment `vec(P).`
