CfU - Charge & Coulombs Law

Charge is a fundamental property of matter... all atoms have charged particles. Which parts of an atom have a positive or negative charge?

• Protons & electrons

• Protons & neutrons

• Neutrons & electrons

• Only protons

• Protons, neutrons, and electrons are all charged

Charge is a fundamental property of matter, ultimately due to the charge of certain particles in an atom. Something as simple as rubbing two objects together can move some particles from one substance to the other. Which part of the atom is moved from one substance to another when rubbed?

• Protons

• Neutrons

• Electrons

• The whole nucleus

Coulombs Law describes the math relationship between charges and the force between those charges (either attracting or repelling). Which changes would make the force between two charges STRONGER?

• Increase the distance (r) between the charges

• Increase the amount of charge on either or both charges (q)

• Decrease the amount of charge on either or both charges (q)

Coulombs Law describes the math relationship between charges and the force between those charges (either attracting or repelling). Which option would result in attraction.

• A balloon is rubbed on a cat which causes electrons to be pulled of the cat's hair and caught on the balloon. Thus, the balloon has a net negative charge and the cat is net positive.

• Two balloons are rubbed on a cat which causes electrons to be pulled of the cat's hair and caught on the balloon. The two negative balloons are held near each other.

• A balloon is rubbed on two cats which causes electrons to be pulled of the cat's hair and caught on the balloon. The two cats are placed near each other to see what their fur does.

Atoms can have a net charge of zero even though it has charged bits within it. This is possible when...

• There are enough neutral neutrons to overwhelm the charged protons and electrons

• There is an equal number of protons and electrons

• There is an equal number of protons and neutrons in the nucleus
