At a given distance from the centre of short electric dipole, field intensity on axial line is k times the field intensity on equatorial line, where k =

For a short electric dipole, the electric field intensity on the axial line is twice that on the equatorial line at the same distance. This follows from the standard dipole field equations:
E_axial = (2kP) / r³ and E_equatorial = (kP) / r³, giving E_axial / E_equatorial = 2.
Answer: (a) 2.
