Static Charge (physics Only) (GCSE Physics)

How does grounding (earthing) prevent buildup of dangerous static charges on large metal objects?

What happens to the electric field strength of a point charge as you move farther away from the charge?

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

Which diagram best shows electric field lines around an isolated negatively charged sphere?

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

How does an earthed conductor behave when a negatively charged rod is brought near but not touching it?

A charged metal sphere is touched by a second identical uncharged metal sphere and then separated. What is the charge on each sphere afterwards?

Which of the following best describes charging by polarisation in an insulator near a charged object?

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?

If two identical metal spheres, one charged +6Q and the other neutral, are touched together and separated, what is the charge on each afterward?

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