4. The action that occurs between two opposite charges (positive and negative).
5. The type of square relationship between distance and electrostatic force.
7. The SI unit used to measure the electric force F calculated in the formula.
8. The value represented by k in Coulomb's Law
10. The variable r in the denominator of Coulomb's Law.
11. The term for the total or resultant force acting on a specific charge.
13. The principle used to find the net force when three or more charges are present.
15. A quantity, like electric force, that has both magnitude and direction.
