What do you observe and/or feel happening? * I feel my hairs from my arm rising and like a tickle and I observed my arm hairs going up while the cup was on my arm. Run the cup lightly over the back of your arm. Recharge the second Styrofoam cup by rubbing it with the fur. Rubbing small objects can pick up small mass objects. You can’t expect to pick up a book with the ruler because the mass of the book is heavy. That is what we call static two objects rubbing each other. Obviously you had to rub hard until you could feel heat transferring. How would you explain the fact that a charged ruler can attract an uncharged object like the paper bits, salt and pepper? * Because of the power the charge has while the ruler was being rubbed in the desktop. Since the uncharged strip had not been charged with anything. How would you explain the attraction or repulsion between each of the suspended tapes and the uncharged paper strip? * Because the suspended tapes had been charged on the desktop and the uncharged strip was just attracted to the tapes that were charged. Why do you think the charged ruler affected the two suspended tapes as it did? * I think it affected the tapes because of the amount of time and force I rubbed the ruler with the rabbit fur. It would be the same thing it won’t affect anything the only difference is with what is being charged which will not make a difference. For example if you charge it with a glass or maybe a plastic bag or also your hair you can also get static so the tape can also attract with the objects hat I mentioned.

If a third type of charge existed, how would it affect the two oppositely charged strips in this activity? * It depends with what you are going to charge it with. And also the ruler that I also charged to be able to attract it to the tape but the ruler I attracted it with the rabbit fur.
