Given that the distance between the two charged particles is increased by 4 times the amout, let's determine how the electrical force between them will change.
The electrical force between two charged particles is determined by the formula:
Where:
k is the constant
q1 and q2 are the two charged particles
r is the distance between the particles
From the formula, we can see that the electrical force between them is inversely proportional to the the square of the distance between the charged particles.
Thus, in order to increase the electrical force, the distance must be decreased.
If the electrical force is changed by a factor of
