Please assist me in this physics problem with the correct steps and answers. PHY 131: electric potential

4 The image below shows a potential map of the area around three charged, conducive spheres centered at points A, B, and C. Assuming the sphere at point A to have a positive charge, answer the following. Go A D C E V=0 B Is the charge of sphere B positive or negative? Sphere C? a. At what point(s) is the electric field zero? b. In what direction does the electric field point at F? C. In what direction does the electric field point at G? d. Rank each point from largest to smallest in terms of the electric potential (negative values being smaller than zero). e
