Static Charge (physics Only) (GCSE Physics)

Which materials are most likely to allow static charges to move and therefore are used to remove charge quickly?

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

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

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

Which particle is the main mobile charge carrier in most solid conductors during static charging experiments?

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

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

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

A piece of insulating plastic rod becomes negatively charged when rubbed with a cloth. Which of the following explains why the rod becomes negative?

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