Question

Potential at a point due to electric dipole consists of

Answer 1

Let us consider a point T which is located r distance from midpoint point of dipole and dipole makes an angle $\theta$ with line as shown in figure.

now potential at point T due to electric dipole is given by, $V=\frac{kpcos\theta}{r^2}$

here, k is kappa constant e.g., k = 9 × 10^9 N/m², P is dipole moment and r is the separation between midpoint of dipole to point of observation e.g., T.
