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.
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.
Carlos investigates electric charge. He uses the apparatus shown in the diagram below.
There are two of each type of rod - Perspex and metal. Carlos rubs one Perspex rod with a woollen cloth before placing it in the cradle.
Explain how Carlos should use the apparatus to make the Perspex rod in the cradle move without touching the rod, the cradle or the string.

Explain why Carlos cannot move a metal rod using the same method.
Read the article about Aiko and then answer the questions.
Aiko was out walking with friends when a heavy rainstorm started. They took shelter near some trees. Her friends crouched down near to the ground but Aiko stayed standing up. She felt her hair starting to stand up on end and then there was a bright flash of light and a loud bang. She felt hot and very scared, but was not hurt. The lightning had struck a tall tree nearby.
Explain why Aiko's hair stoop up before the lightning strike.
