SUMMARY
The electric potential of an electric dipole at a large distance is expressed as V = (qa cos(θ))/(4πεr²), where 'a' represents the separation of the two charges ±q, and 'r' is the distance from the dipole. As the distance 'r' approaches infinity, the potential approaches zero, since the contributions from both charges cancel each other out. This conclusion is derived from the approximation that at large distances, the point of interest is equidistant from both charges, leading to V = kq/r + k(-q)/r = 0.
