Problem: Suppose a van de Graaff generator is turned on and a positive charge builds up on its dome. A grounded conducting wand is brought close to the dome of the Van de Graaff generator and 9.00µC of negative charge arcs from the wand to the dome.
Part A: How many electrons are involved in the arcing process?
I need help to determine how many electrons are involved in the arcing process.
