Physics 1B Lecture 15C "Winny and I lived in a house that ran on static electricity... If you wanted to run the blender, you had to rub balloons on your head. If you wanted to cook, you had to pull off a sweater real quick." --Steven Wright

From Last Time Coulomb’s Law: where k e is the proportionality constant with a value of: k e = 8.99x10 9 N m 2 /C 2 .
Coulomb’s Law The direction of Coulomb’s Law is determined by the sign of the two charges involved. If you have unlike charges then the force will be attractive along the line connecting the two charges. If you have like charges then the force will be repulsive along the line connecting the two charges.

Coulomb’s Law Note the similarities between Coulomb’s Law and Newton’s Law of Universal Gravitation. Both have a proportionality constant. Both depend on the inverse square of the separation distance, r. Both forces “act at a distance,” the objects do not need to be touching. But because k e > G we say that the electric force is a stronger force.
Coulomb’s Law When performing a Coulomb’s Law problem make sure you: 1) Define a coordinate system.
