Question
What happens to the electrostatic force between two
charges when the distance between them decreases?ÂSolution
The force between two charges is given as F= K m M/ d²  . Hence, if the distance decreases the overall denominator decreases and therefore force increases. We can say that force is inversely proportional to the square of the distance between the two charges. Hence, option A is correct.Â
