Answer: The electrostatic force will be the same
Explanation:
According to Coulomb's Law, when two electrically charged bodies come closer, appears a force that attracts or repels them, depending on the sign of the charges of this two bodies or particles.
In this sense, this law states the following:
"The electrostatic force between two point charges
and
is proportional to the product of the charges and inversely proportional to the square of the distance
that separates them, and has the direction of the line that joins them"
(1)
Being is a proportionality constant.
Now, if each and
are increased by 6, and the distance between them as well, we will have the following:
(2)
(3)
Simplifying:
(4)
Comparing (1) with (4) we can see the electrostatic force is the same.
