If the distance between two charges is halved, what will happen the force between the charges?
2 Answers
Explanation:
From Coloumb's law of electrostatic force we know,
So,if the distance between the charges is halved, with no changes of the charges,new distance becomes
So,if now force acting between the same charges is
Then
So,that means, force will be
The force between the two charges is quadrupled.
Explanation:
The force between the two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Hence, if distance between charges is halved (charges remaining kept constant),
the force between the two charges is quadrupled.
