How are electric forces and distance related?
Electric forces are inversely proportional to the square of the distance from the source of the force.
Wow, what does that mean? In math it looks like this.
Electric Force =
In simpler terms, this means the force gets four times weaker every time you double the distance. This property is known as the Inverse-Square Law. A lot of different things in physics fallow this law. For more on this check out the link below.
