The gravitational force between the charged constituents of the atom is negligible compared with the electric force between them. the electric force is so strong, however, that any net charge on an object quickly attracts nearby opposite charges, neutralizing the object. as a result, gravity plays a greater role in the mechanics of moving objects in everyday life. question if the distance between two charges is doubled, by what factor is the magnitude of the electric force changed?

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?
