Coulomb's Law describes the force between two charged objects:
* F = k * (q1 * q2) / r²
Where:
* F is the electric force
* k is Coulomb's constant
* q1 and q2 are the charges of the two objects
* r is the distance between the centers of the two objects
The key is the inverse square relationship: The force is inversely proportional to the square of the distance.
* If you triple the distance (r becomes 3r), the denominator in the equation becomes (3r)², which is 9r².
* This means the force is divided by 9.
In conclusion: Tripling the distance between two charged objects reduces the electric force between them by a factor of 9.
