Question

Describe the effects in the pictured sequence of the experiment below by adding local net charges (either + or -) to the drawings. Be clear about the sign of charge on the "head" of the electroscope and the "leaves" and their relative magnitudes. What is the overall net charge of head and leaves? The "ground" can supply electrons or may take up electrons. Is there net charge on the electroscope head? The spreading of the leaves indicate that they possess net charge. What sign of charge? What happened to the charge that was on the leaves before grounding? The connection to the ground is removed; after that the charged PVC rod is removed. After the procedure the electroscope is charged. What is the name of this charging process? What sign is the final charge on the electroscope head? on the leaves?
