SUMMARY
The electric potential (V) of an arc of uniform charge can be expressed as V = kQ/R, where k is Coulomb's constant, Q is the total charge, and R is the distance from the arc to the point of interest. This treatment of the arc as a point charge is valid because electric potential is a scalar quantity, allowing contributions from different charge elements to be summed directly. The concept parallels that of a conducting sphere, where charge distribution is uniform, even at the center. The integral approach to deriving the potential from point charges confirms this equivalence.
