The new force becomes One Ninth (1/9) of the original force.
The force between two point charges (let's say ) is given by the following formula:
Force divided by (
squared)
Here r is the distance.
If we multiply r by three then after squaring it will become squared.
Let's rewrite the formula and call it new Force:
New Force divided by
squared )
Now just separate the 9 :
New Force divided by
Squared ))
New Force (Force)
So turns out that the new force becomes One Ninth (1/9) of the original force.
A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to define force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
