23.21. Two point charges 91 60 n +2.40 nC and 92 42 are 0.100 m apart. Point A is midway between them; point B is 0.080 m from 9₁ and 0.060 m from 42 (Fig. 23.31). Take the electric potential to be zero at infinity. Find (a) the potential at point A; (b) the potential at 0.050 m-0.050 m→ A point B; (c) the work done by the electric field on a charge of 2.50 nC that travels from point B to point A.
