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 on the axial line (Eₐ) is twice the electric field on the equatorial line (Eₑ) at the same distance from the center of the dipole. Thus, the correct answer is (a) 2.

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.
