Consider two oppositely charged spheres separated by a small distance. The charge on each sphere has the same magnitude but opposite sign.
a. a** Sketch a diagram to show the electric field lines that define the shape of the electric field between and around the two spheres.
b. b Using your knowledge of the relationship between electric field lines and equipotentials, add some equipotentials to your diagram from part a**.
c. c** How does your diagram help you to identify where the electric field strength is greatest?
