The electric force between two charged particles is 0.18 newtons. If the distance between them is increased by a factor of 3.0, what will the new electric force be?
Since electric force is inversely proportional to distance squared then the force will be 9 times smaller; i.e. the new force will be 0.18/9 = 0.02 newtons.
