1.Find the potential at point A?2. Find the potential at point B?3.Find the work done by the electric field on a charge of 2.50nC that travels from point B to A?

Problem 18.19 Two point charges of - - 2.20nC and g2 - -6.25nC are 0.100 m apart. Point A is midway between them: point B is 0.080 m from g, and 0.060 m from oz. (See (Figure 1)/) Take the electric potential to be zero at infinity
