CP Ch09.1 Electric Charge

What are atoms composed of?

• Positively charged electrons

• Negatively charged protons

• Neutrons in the nucleus

• Positively charged nucleus surrounded by negatively charged electrons, with protons and neutrons in the nucleus

How do electric fields surrounding charges interact with each other?

• Directly proportional to the distance between charges

• Following the inverse square law

• Dependent on the type of charge

• Constant regardless of the charge magnitude

What is a fundamental principle in physics similar to conservation of energy and momentum?

• Conservation of mass

• Conservation of charge

• Conservation of temperature

• Conservation of volume

How does rubbing a balloon on your hair charge the balloon?

• By transferring protons

• By transferring neutrons

• By transferring electrons

• By transferring photons

What happens when an atom loses electrons?

• It becomes positively charged

• It becomes negatively charged

• It remains neutral

• It becomes a neutron

What is involved in charging objects according to the principle of conservation of charge?

• Creating electrons

• Destroying electrons

• Transferring electrons without creating or destroying them

• Ignoring the principle of conservation of charge

Why do oppositely charged objects attract each other?

• Due to the transfer of protons between them.

• Due to the transfer of neutrons between them.

• Due to the transfer of electrons between them.

• Due to the transfer of photons between them.
