Electrostatic charging is highly useful in industrial paint-spraying systems, such as those used to paint car bodies.
The droplets of paint are given the same type of electrostatic charge as they are expelled from the spray gun nozzle. Explain how this helps to produce an even distribution of paint.
The metal car body is earthed. Explain how this reduces the amount of paint wasted during the spraying process.
