Document Summary

In this situation, the balloon should get attracted to the rod. Now if we let the balloon to touch the rod, some electrons will move into the glass rod. Hence, the balloon gets positively charged and it should repel the glass rod. So it is clear that there are two charge types. While electrons are not free to move, they are pulled towards one side. We will spend a lecture on this later on. An interesting experiment for you to try is when you wear a nylon shirt. Go to a pitch dark room in front of a mirror try taking the shirt off. Try combing dry hair into one place! or how many of you have been zapped by door knobs!. Charge is a fundamental quantity in electricity and magnetism. There are two kinds of electric law, charges obeys coulomb"s and negative. Figure 2. 3: the interaction of two point charges.
