Physics H 09 Charge Behavior and Electrical Force

Two fundamental properties of matter are mass and __

• momentum

• velocity

• energy

• charge

Which of these statements about atoms are correct?

• Protons have a charge of +1 and are found in the nucleus

• Electrons have a charge of -1 and are found in the nucleus

• Electrons have a charge of -1 and are found outside the nucleus

• Neutrons have a charge of 0 and are found in the nucleus

This fundamental force operates between electrically charged particles

• Gravity

• Electromagnetic

• Strong interactive force

• Weak interactive force

–

An object with a net electric charge is said to be

• static

• neutral

• charged

• insulated

Which of these statements about charges are correct?

• Similar charges attract

• Disssimilar charges attract

• Similar charges repel

• Disssimilar charges repel

"Net amount of electric charge in any process is zero and

no net electric charge can be created or destroyed". This is the Law of Conservation of __

• Energy

• Momentum

• Electric Charge

• Mass

If you rub a plastic rod with a cloth, electrons move from the rod to the cloth. This means that the

• Plastic rod becomes negatively charged

• Plastic rod becomes positively charged

• Cloth becomes positively charged

• Cloth becomes negatively charged

Conductors

• transfer electric charges from one place to another easily

• transfer electric charges from one place to another poorly

• an intermediate category between conductors and insulators

Insulators

• transfer electric charges from one place to another easily

• transfer electric charges from one place to another poorly

• an intermediate category between conductors and insulators

Semiconductors

• transfer electric charges from one place to another easily

• transfer electric charges from one place to another poorly

• an intermediate category between conductors and insulators
