(C) The electric field at an axial point $p$ at a distance $r$ from the center of a dipole is given by $E_P = \frac{2Kp}{r^3} = E$.The electric field at an equatorial point $R$ at a distance $2r$ from the center of the dipole is given by $E_R = \frac{Kp}{(2r)^3} = \frac{Kp}{8r^3}$.Substituting $Kp = \frac{Er^3}{2}$ into the expression for $E_R$:$E_R = \frac{1}{8r^3} \cdot \frac{Er^3}{2} = \frac{E}{16}$.Comparing this with $\frac{E}{x}$,we get $x = 16$.

The electric field at point $p$ due to an electric dipole is $E$. The electric field at point $R$ on the equatorial line will be $\frac{E}{x}$. The value of $x$ is:
