Part A Charged applied | Observations | Charged ebonite rod close to, but not touching, the terminal of the electroscope. Negatively charged ebonite rod. Neutrally charged metal leave electroscope. | The leaves raised | Move the ebonite rod closer to (but not too close) and further away from the electroscope terminal.Negatively charged ebonite rod.Neutral metal leaf electroscope. | It raised and then when you remove the ebonite rod it goes back down. |
Part B Charged applied | observations | Ebonite rod close to the electroscope terminal. Without moving it touch the opposite side of the terminal with your fingers. Move your fingers away and observe. | It raised and when you touch it with your fingers then it goes back down. | Move the ebonite rod away from the electroscope and record. | It got neutral and the leaves go down. | Charge the ebonite rod. Bring the rod close and observe. | It rose because of the charge that goes to the electroscope. | Try moving the ebonite rod closer to and further away from the electroscope and observe the leaves. | It stays raised and the charge does not go from the electroscope. |
Analyze and evaluate (a) Step 4 part A: series of diagrams showing how the charges in the electroscope were affected by the negatively charged ebonite rod.
(b) The leaves rose when I got the ebonite rod close to the terminal of the metal leaf electroscope and went back down when I got the ebonite rod further away from the electroscope. (c) Step 8 part B: charges in the electroscope were affected by the negatively charged ebonite rod and the presence of your finger.
(d) Step 9 part B: diagram showing how the charges are now distributed in the electroscope leaves.
(e) The similarities are that when you get the ebonite rod close to the electroscope the
