Question 246 of 311
For a short dipole placed at origin , the dipole moment is along -axis, as shown in the figure. If the electric potential and electric field at A are and , respectively, then the correct combination of the electric potential and electric field, respectively, at point on the -axis is given by

Show answer and solution
Answer: (B) zero and
At point (axial)
At point (equatorial)
$\begin{aligned}
& |E|=\frac{k_p}{(2 r)^3}=\frac{E_0}{16} \\
& V=0
\end{aligned}$
