Webb12 feb. 2024 · Solution: the work done by the electric force in moving a charge q q between two points with different electric potentials is found by W=-q\Delta V W = −qΔV, where \Delta V=V_2-V_1 ΔV = V 2 − V 1. In this case, the charge travels from point B B to point A A, so we must first find the potential difference between these two points.
