Coulomb's Law
The force between two charged particles is described by Coulomb's Law:
* F = k * (q1 * q2) / r²
Where:
* F is the electric force
* k is Coulomb's constant (a constant of proportionality)
* q1 and q2 are the magnitudes of the charges
* r is the distance between the charges
The Impact of Distance
Notice that the force is inversely proportional to the square of the distance. This means:
* If you halve the distance (r/2), the force increases by a factor of 4 (2²).
In Conclusion
If you bring two charged particles to half their original distance, the magnitude of the electric force between them will increase by a factor of four.
