Electric field for electric dipole

The angular position of a point at which electric field of an electric dipole is normal to its dipole moment vector 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

At what angle between dipole moment and electric field, electric dipole remains in stable equilibrium in uniform electric field ?

What work must be done to rotate an electricdipole thurgh an angle theta with the electric field, if an electric dipole of moment P is placed in an uniform electric field E with P parallel to E ?

The correct formula for potential energy in the electric field of an electrical dipole body is, when the angle of the electric dipole is theta with the electric field (k=(1)/( 4pi in_(0)))

The dimensions of length in electric field, electric flux and electric dipole moment are respectively
