Lab #9: Electric Charge & Electric Fields Prelab Questions to be completed on a separate sheet of paper and turned in prior to the start of lab): 1.) What are the different types of electric charge? How is this different from "gravitational charge" (i.e. mass)? 2.) When you bring two like electric charges close to each other, do they attract, repel, or ignore each other? How is this different from two masses experiencing gravitation? 3.) When you bring two opposing electric charges together, how do they interact with one another attract, repel, or ignore)? 4.) Which force is stronger, the electric force or the gravitational force? Explain it based on real life experience. 5.) Explain why people's hair stands up on edge when they become statically charged
