• Deduction

• Electroscope

• Induction

• Polarized

Electrical forces between two charges are strongest when the charges are

• farther apart.

• close together.

• The electrical forces are constant everywhere.

The charge of a neutron is

• Positive

• Neutral (no charge)

• Negative

Coulomb's Law says that the force between any two charges depends on

(choose all that apply)

• directly on the magnitude of the charges.

• Inverse of the square of the distance.

• the force is always the same no matter the charge value

• There is no such thing as Coulomb's Law

In a good insulator, electrons are usually

• moving freely through the material.

• Not freely moving through the material.

• Semi-free to move through the material.

When two like charges are a certian distance apart from each other, they want to

• attract each other

• repel each other

• must be neutrons

• Ohm

• Newton (N)

• Coulomb (C)

The conservation of charge means that (choose all that apply)

• the total amount of charge in the universe is constant

• electrons by themselves can neither be created nor destroyed

• charge cannot be created or destroyed

• no experimenter has seen a single charge destroyed by itself
