Here's why:
* Coulomb's Law: The electric force between two point charges is directly proportional to the product of the charges. This means if you increase one charge, the force increases proportionally.
* Formula: Coulomb's Law is expressed as:
F = k * (q1 * q2) / r²
where:
* F is the electric force
* k is Coulomb's constant
* q1 and q2 are the magnitudes of the charges
* r is the distance between the charges
* Doubling the charge: If you double one charge (let's say q1), the new force (F') becomes:
F' = k * (2q1 * q2) / r² = 2 * (k * q1 * q2 / r²) = 2F
Therefore, doubling one charge doubles the electric force between the two charges.
