The diagram represents two small charged spheres, A and B, 3 meters apart. Sphere A has a charge of -2.0 × 10^-6 C. Sphere B has a charge of +2.0 × 10^-6 C. Which diagram best illustrates the electric field between charges A and B?

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
