* As the distance increases, the electric force decreases rapidly.
* As the distance decreases, the electric force increases rapidly.
This relationship is described by Coulomb's Law:
F = k * (q1 * q2) / r²
Where:
* F is the electric force
* k is Coulomb's constant (approximately 8.98755 × 10⁹ N⋅m²/C²)
* q1 and q2 are the magnitudes of the charges of the two objects
* r is the distance between the centers of the two objects
In simpler terms:
Imagine you have two magnets. If you hold them close together, they exert a strong force on each other. As you move them further apart, the force weakens. The force weakens much faster than you might expect because it's inversely proportional to the square of the distance.
Example:
If you double the distance between two charged objects, the electric force between them will be reduced to one-fourth of its original value.
Important Note:
This relationship only applies to the electric force between point charges. If the objects have a more complex shape, the calculation of the force can be more complicated.
