  • Calculate the electrostatic force between electrically charged particles.

Everything You'll Have Covered

How do the forces of attraction differ between particles of like charges and particles of opposite charges?

~ Particles of like charges repel one another. Particles of opposite charges attract one another.

What is electrostatic force?

~ Electrostatic force is the force that is felt between charged particles.

What does Coulomb's Law state?

~ Coulomb's Law states that the magnitude of electric force experienced by two charged particles is directly proportional to the product of the amount of charge on each particle and inversely proportional to the square of the distance between the charges.

Based on Coulomb's Law for two given charged particles, what is the relationship between the amount of charge on each particle and the magnitude of the force they apply to each other?

~ Based on Coulomb's Law, the magnitude of the force the particles apply to each other is equal, regardless of which particle has more charge.
