Important Questions on Electrostatics and Electric Currents
Lily uses the apparatus in the image below to investigate how a charged insulator can affect the behaviour of everyday objects. Look at the diagram carefully and answer the question.
Describe and explain a method Lily can use to charge an object.
Lily uses the apparatus in the image below to investigate how was charged insulated can affect the behaviour of everyday objects. Look at the diagram carefully and answer the question.
Look at the table. The first column shows objects that Lily gives charge to. She then brings each charged object slowly closer to each of the objects in the second column.
Complete the table by describing what you would expect Lily to observe for each object.
| Charged Object | Test Object | Observation |
| Ruler | Small pieces of paper | Pieces of paper are attracted to the ruler. |
| Sheet of plastic food wrap | Another sheet of plastic food wrap | |
| Balloon | Wall | |
| Ruler | Metal paper clips |

Lily wants to test how tap water is affected by a charged object. Explain the observation.
Static electricity is used by car manufacturers to help paint some parts of cars. The paint is sprayed onto the car parts using a device called spray gun. The spray gun and paint are given a positive electric charge.
What charge should be given to the car parts to attract the particles of paint.
Static electricity is used by car manufacturers to help paint some parts of cars. The paint is sprayed onto the car parts using a device called spray gun. The spray gun and paint are given a positive electric charge.
Explain how using electric charge in this way means that paint can be applied to part of cars that are hidden from view.
