Coulomb's Law is used to determine the forces experienced by charged particles.

###### Coulomb's Law

Concept #1: Coulomb's Law & Potential Energy

Concept #2: Coulomb's Law Formula

Example #1: A charge of + 4.13 x 10-19 C is placed 8.03 x 10-7 m apart from another charge of –3.37 x 10-17 C. What is the force of attraction between the charged particles?

Practice: A force of 3.24 x 10-12 N exists between a +3 charge and another charged particle. The ions are 2.53 x 10-8 m apart. What is the charge of the unknown charged particle?  (Rework numbers since you went from +15 to +3)
