I have heard a lot about how gravity is the weakest force and after thinking about it for a while, I don't really see why it is. One argument I heard for gravity being the weakest is how the value for G in F=G*m*m/r^2 is so much lower than the value of k in F=k*q*q/r^2 but considering how the units on k and G are different, I don't see how that is a valid point. For example if you were to change the units on k into Nm^2/(picoCoulomb^2) the value of k would be a lot lower than the value of G. Another argument I heard was how the electrons in objects such as a chair are able to repel each other and fully overcome the downward force of gravity. But when you consider how close the electrons are to each other compared to how far the object is to the center of the earth and how the force is inversely proportional to the square of the distance, it doesn't really show which is stronger. And again, the units are different so unless there is a way to compare coulombs to kilograms, I don't understand how one can be declared stronger than the other. So if someone has a better way of explaining it, I would greatly appreciate it.
