1. The problem statement, all variables and given/known data set up:(they three are all connected) l (referred to as top) /\ (the bottom two called "leaves") - two leaves are separated when negatively charged rod touches the top of the (vertical thing that connects the two leaves at the bottom) - when rod is taken away, and a finger is put on the top, the leaves collapse and touch each other. - when hand is taken away, the leaves separate a little (not as much as the first step) Q: what are the charges on the two leaves? 2. Relevant equations 3. The attempt at a solution I guessed that that both leaves are negatively charged.. because they repel at the last step. the finger charges by contact? providing positive charges.
