Static Charge (physics Only) (GCSE Physics)

What is the typical effect of humidity (higher moisture in air) on static charge accumulation?

How can you discharge (neutralise) a negatively charged plastic rod safely?

Which statement best describes charging by conduction (contact)?

What happens to the total number of electrons and protons in an isolated insulated system when objects are charged by rubbing?

A classroom demonstration shows a negatively charged rod brought near small pieces of paper which are attracted then repelled and jump off. Why do they sometimes repel after touching the rod?

When two different insulating materials are rubbed together, they become charged by the process called:

What is a safe practice to reduce the risk of a harmful static discharge when working with electronics?

Which surface will generally become the most negatively charged after being rubbed with a given cloth?

When two small charged pith balls are suspended and they repel each other, what can be deduced about their charges?

Which of these is the best explanation for the visible spark (small lightning) when you touch a large charged metal dome?

When the distance between two small charged objects is doubled, how does the electrostatic force between them change (qualitatively, Coulomb’s law)?
