A hydrogen atom is located close to the surfsce of the earth. a) What is the ratio of the magnitude of the electric force between the electron and proton compared to the magnitude of the gravitational attraction between the electron and proton compared to the magnitude of the gravitational attraction between the electron and the earth? (This is how many times greater the electric force is in this situation) b) Draw a conclusion about the stability of matter. (How come gravity doesn't pull molecules apart?) c) Why is the gravitational force between the Earth and Moon greater than the electric force? (Since all matter is made of protons and electrons, why isn't electric force always greater?)
