In which one of these processes is static electricity most likely?

1.   ?    Water flowing in a stream.
2.   ?    A plant growing in sunlight.
3.   ?    Jet fuel being pumped rapidly on board a large aeroplane.
4.   ?    A battery connected to a light bulb in a torch.

Which one of these moves when static electricity is made?

1.   ?    Electrons
2.   ?    Protons
3.   ?    Neutrons
4.   ?    Morons

A polythene rod becomes negatively charged after being rubbed with a cloth. Which one of these correctly describes the process?

1.   ?    Electrons are rubbed from the cloth, while protons from the rod are rubbed onto the cloth.
2.   ?    Electrons are rubbed from the cloth while the protons in the rod stay where they are.
3.   ?    Protons are rubbed onto the cloth while the electrons in the rod stay where they are.
4.   ?    Electrons are rubbed onto both the cloth and the rod.

An acetate rod becomes negatively charged after being rubbed with a cloth. Which one of these correctly describes the process?

1.   ?    Protons are rubbed from the cloth, while electrons from the rod are rubbed onto the cloth.
2.   ?    Protons are rubbed from the cloth while the electrons in the rod stay where they are.
3.   ?    Protons are rubbed onto the rod while the electrons in the rod stay where they are.
4.   ?    Electrons are rubbed off the rod onto the cloth, and the protons on the rod stay where they are.

Which one of these is correct?

1.   ?    Like charges attract; unlike charges repel.
2.   ?    Like charges repel; unlike charges attract.
3.   ?    Like charges attract; unlike charges attract as well.
4.   ?    Like charges repel; unlike charges repel.

Which one of these is correct?

1.   ?    Positive charges arise due to an excess of protons moved by the separation of charges.
2.   ?    Positive charges arise due to a deficiency of electrons moved by the separation of charges.
3.   ?    Negative charges arise due to a difficiency of protons moved by the separation of charges.
4.   ?    Only negatively charged objects can be discharged by connecting a wire to earth.

Which one of these statements correctly describes the relationship between charge and potential difference?

1.   ?    The potential difference is always less than the charge.
2.   ?    The greater the charge, the lower the potential difference.
3.   ?    The greater the charge, the greater the potential difference.
4.   ?    There is no relationship.

What happens if the potential difference gets bigger than the breakdown voltage of air?

1.   ?    Nothing.
2.   ?    A spark will jump due to the discharge of protons.
3.   ?    This is impossible, since air is a very good insulator.
4.   ?    A spark will jump due to the discharge of electrons.

The rapid pumping of fuel onto an aeroplane can be dangerous due to a build up of charge. Which one is the best way of avoiding this danger?

1.   ?    Pump the fuel slowly.
2.   ?    Put fine metal particles in the fuel.
3.   ?    Connect a wire from the aeroplane to the tanker.
4.   ?    Only refuel an aeroplane on a moist day when there is less chance of a spark.

A balloon is charged up with a neagtive charge and sticks to the wall. This is because:

1.   ?    the negative charges attract protons from the wall.
2.   ?    the negative charge repels electrons deeper into the wall, leaving the protons where they are.
3.   ?    the negative charge repels the protons into the wall and attracts the electrons.
4.   ?    The distribution of charge makes tiny microscopic hairs stand up on the surface of the balloon. These find tiny holes in the wall and achor the balloon firmly to the wall.
