If a negatively charged Styrofoam plate is brought towards pieces of paper placed on an insulator (ex. a piece of paper), attraction occurs. Repulsion occurs if pieces of aluminum foil, which is a conductor, are placed on an insulator. What would occur if the pieces of paper and aluminum foil were placed on a conductor, such as a sheet of aluminum foil? Would the pieces of paper still be attracted to the plate while aluminum pieces repelled? Would the strength of attraction or repulsion differ?
