Question 9 Why did the leaves remain separated after you removed your finger and the rod? Use the idea of ground in your description. Part 5 - Positive and Negative So far in the lab we haven't talked about what kind of charge [positive or negative] has accumulated on the rods or the leaves. Given the fact that the combination of the gray rod and the fur gives you a negatively charged rod, think of a procedure to determine what type of charge, positive or negative, accumulated on the rod for each combination in your chart that gave you either A LITTLE or A LOT. Put a "+" or a "-" in your chart accordingly. Question 10 Explain your procedure to determine positive or negative charge. Part 6 - Faraday's Cup Remove the metal ball from the electroscope and replace it with the metal platform from your equipment box. Place the metal cup on the platform. Charge up combinations from your chart that gave you A LITTLE or NONE. Position the rod inside the metal cup, but don't let the rod touch the cup. Note what happens to the leaves. Did some of the A LITTLE combinations make the leaves separate more than they did with the ball? Did some of the NONE combinations make the leaves raise? Question 11 Explain why the cup is making the leaves separate more than the ball
