  8. Electroscope • Draw a diagram showing the forces that exist on the leaves of the electroscope when it is placed close to the Van de Graff generator

  9. Pith Ball • Draw a free body diagram of the pith ball when it is brought close to the Van de Graff generator • Do we have the skills to address this situation?
