Benjamin Franklin named the positive and negative charges, giving the base for a law that states:
Equal charges have repulsive forces, while different charges are pulling each other.
I won't touch anything that could give me an electrical shock.
Charges with equal symbols have repulsive forces, while charges with different symbol are pulling each other.
There are repulsive and pulling forces according to the charges.

How many times the force is affected if the distance between two charges decreases FIVE times; according Coulomb's law.
The force of love is stronger than the distance, we can be happy XD
Force increases five times
Force increases ten times
Force increases twenty-five times
How many times the force is affected if the distance between two charges increases TEN times; according Coulomb's law.
Force is inverse proportion to the distance, then 10 times
Force increases 100 times
Force stays equal
Force decreases 100 times
Coulomb's equation:
