# If $E_e$ be the electric field strength of a short dipole at a point on the equitorial line and $E_a$ be that on axial line at same distance then :

$(A)\;E_e=2 E_a \\ (B)\;E_a=2 E_e \\ (C)\; E_e = E_a \\ (D)\;None$

Electric field due to dipole on equitorial line .
$E_e =k \bigg( \large\frac{p}{r^3}\bigg)$
Where as on axial due
$E_a = k \bigg( \large\frac{2p}{r^3}\bigg)$
Hence B is the correct answer
