2.23 practical: investigate how insulating materials can be charged by friction

Hold polythene rod and cloth next to up small pieces of paper one at a time, observe.
Now rub the rod with the cloth
Again hold close to small pieces of paper, observe.
Turn on a tap so a thin stream of water is flowing
Hold the rod about 1cm away from the water just below the nozzle, observe
Repeat with different material rods and cloths

2.28 explain some uses of electrostatic charges, e.g. in photocopiers and inkjet printers

Paper is charged negatively in certain regions. Then positively charged paint droplets are sprayed onto the paper and attracted to the negative regions of the paper giving the desired image.
