2.20 describe experiments to investigate how insulating materials can be charged by friction

Get a polyethene rod and rip up some small pieces of paper; the rod will have no effect on the paper.
Rub the polyethene rod with a cloth, now the rod will attract the pieces of paper, this is because it now has a charge they are attracted to.
