What does Coulomb's Law apply to?

electrostatic force between charges

A beam of light that strikes a surface at a 37° angle to the normal is...

reflected at a 37° angle to the normal.

Electrostatic force between charges decreases as

the square of the distance increases.

A light ray that is completely reflected has which characteristic?

It does not pass through the reflecting medium.

"Static" electricity means that electric charges are

separated from each other and trapped there.

The index of refraction tells us

how light's speed in a medium compares to c.

Which of the following would have a net electric charge?

ions dissolved in a solution, alpha particles
