What does "R" measure?
the distance between the two charged objects
the amount of charge carried by the objects
the amount of force between two charged objects
the constant value for forces between the objects
What will be the units of F (or Fe)?
Newtons
Meters
Coulombs
Joules
What does q measure?
the distance between the two charged objects
the amount of charge carried by the object
the amount of force between two charged objects
Why are there two q's in the equation?
because there are two charged objects
because there are protons and electrons
because the particles are moving away from each other
because the particles are moving towards each other
