What do you remember about Coulomb's Law?

Where does this equation come from? What is Coulomb's Law divided by "q?"

(Do your best to type out the math.)

This is a concept of theoretical physics.  What have we done here?  Why can we just ignore the test charges charge?

Why is the test charge positive?

From Positive to Negative.  What does this remind you of from our study of electricity so far?

Why do the charges evenly distribute themselves?

Are there ANY forces acting on these during electrostatic equilibrium?

Are there any NET forces acting during electrostatic equilibrium?

What does this sound like in what we have talked about so far? This might not be a shocking question...

How could you explain this video in 1 sentence?
