The electric force between two charged particles is directly proportional to the product of the charges. This means if you double one charge, the force will also double.

Here's a breakdown:

* Coulomb's Law: The force between two charges is described by Coulomb's Law:

* F = k * (q1 * q2) / r²

* F is the force

* k is Coulomb's constant

* q1 and q2 are the charges

* r is the distance between the charges

* Doubling One Charge: If you double q1, the entire numerator of the equation doubles, resulting in a force that is twice as large.

In summary: If you increase one charge by a factor of 2, the electric force between the two charges will also increase by a factor of 2.
