To derive the expression for the electric potential at any point along the axial line of an electric dipole, we can follow these steps: ### Step 1: Define the Electric Dipole An electric dipole consists of two equal and opposite charges, +q and -q, separated by a distance of 2a. The midpoint between the charges is taken as the origin. ### Step 2: Identify the Point of Interest Let point B be the point along the axial line where we want to calculate the electric potential. The distance from the midpoint to point B is denoted as r. Thus, the distance from the positive charge (+q) to point B is \( r - a \) and from the negative charge (-q) to point B is \( r + a \). ...
