A matter with equal amount of positive and negative charge is said to be ________________.

• Neutron

• Neutral

• Electron

• Static

What is considered “no charge” sub-atomic particles?

• Neutron

• Neutral

• Proton

A force exerted by magnets when they attract or repel each other is called______________.

• Coulomb's Law

• Electric Charge

• Magnetism

• Electrostatic

What is caused by the motion of electric charges?

• Electron

• Electric Force

• Magnetism

• Protons

Coulomb’s Law states that

• opposite charges repel while alike charges attract

• the force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges

• the force of attraction or repulsion between two charged bodies is indirectly proportional to the product of their charges

• The force is equal to the charge on 6.24 x 10^18  protons
