What happens if an electron is near a proton? Find a simulation that allows you to get an electron to circle around the nucleus. (Refresh the page if it asks you to Subscribe) What does this resemble? What happens to force on the electron as it gets closer to the nucleus? Find a simulation in which you have two charged particles next to one another and where you can alter the charge on at least one of them. What happens to the net electric field as q2 approaches 0 C (neutral)? Use a series of three diagrams to show the changes. Draw the electric fields for the following: Single positive charge Single negative charge Two equal positive charges Two equal negative charges Equal unlike charges Unequal like charges Unequal unlike charges In a simulation that shows you electric field lines and allows you to alter the charge, what do you notice about the relationship between charge and electric field lines? Do field lines ever cross? Why? Score a "Goal" on Difficulty level 3 with this simulator and take a picture! Note: This simulator may take a minute or so to load. If stuck, refresh the tab.
