(a) One way of painting complex-shaped objects involves using a method in which paint is sprayed from a nozzle
which is positively charged. The article to be painted is negatively charged. From your understanding of charge as explained in S104 Book 3 explain how the process works and hence why this is a very efficient way of spraying compared with normal spray painting (with no charge). Include in your answer explanations as to: • why a voltage difference must be applied to the system of the nozzle and the article during the painting process • the electrical property that the surface of the article to be painted must have. We expect you will be able to answer all of part (a) in about 160 words.
