So....Coulomb was a smarty pants.
Coulomb's Law states that "the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects"
Coulomb died on August 23, 1806
There are 2 charges: one positive and one negative. The distance between the two points is 2.4 m. The positive object has a charge of 2.6uC and the negative has a charge of -7.1uC. What is the force between the two points?
~He was able to measure the frictional forces of electricity and magnetism
Coulomb's law has been the basis for other inventions such as the atomic bomb.
That's a lot of words. To put it in simpler words:
k in this equation is Coulomb's Law constant: 3.00(10)^8 m/s
Here's the equation again:
~The same device was previously invented by a guy named John Mitchell, but Coulomb made more use of it.
q is the charge
Coulomb had a part in creating the metric system
d is the distance
The amount of force between 2 objects depends on how much space is between them.
~The balance allowed Coulomb to measure force better than anyone before his time
F=(k)(2.6)(7.1)
-------------
(2.4)^2
This is the law in equation form:
9.61 (10)^8 N
He used it to measure the density of the earth. It led to what he is known for...
