Answer: It will remain the same
Explanation:
According to <u>Coulomb's Law:</u>
<em>"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". </em>
<em />
Mathematically this law is written as:
(1)
Where:
is the electrostatic force
is the Coulomb's constant
are the electric charges , which in this case have the same positive charge
is the separation distance between the charges
Rewritting we have:
(2)
Now, if the first charge is doubled:
And the second is reduced to a half:
We will have the following:
(3)
(4)
As we can see equation (4) is equal to equation (2), this means the force of repulsion between both charges will remain the same
