Packing material made of pieces of foamed polystyrene can easily become charged and stick to each other. Given that the density of this material is about 35kg/m3, estimate how much charge might be on a 2.0 cm -diameter foamed polystyrene sphere, assuming the electric force between two spheres stuck together is equal to the weight of one sphere.
