How does increasing the distance between charged objects affect the electric force between them?

a. the electric force increases because the distance has an indirect relationship to the force.

b. the electric force increases because the distance has a direct relationship to the force.

c. the electric force decreases because the distance has an indirect relationship to the force.

d. the electric force decreases because the distance has a direct relationship to the force.

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?
