A metal banana-shaped earring has a net charge of -2.0 µC while a metal apple-shaped earring has a net charge of 8.0 uC. The earrings are 3.0 m apart. (A) What is the electric force between the two earrings? Is it attractive or repulsive? (B) The two earrings are brought together, touching one another for a few seconds, after which the earrings are once again placed 3.0 m apart. What is the electric force between the two earrings now? Is it attractive or repulsive?
