To address the question using **Coulomb's Law**, let’s analyze both the magnitude of the charges and the distance between them.

Coulomb's Law is given by the formula:

\[
F = k \frac{|q_1 \cdot q_2|}{r^2}
\]

where:
- \( F \) is the force between the charges,
- \( k \) is Coulomb's constant (\(8.99 \times 10^9 \, \text{Nm}^2/\text{C}^2\)),
- \( q_1 \) and \( q_2 \) are the magnitudes of the charges,
- \( r \) is the distance between the charges.

### Analysis of the Factors
1. **Magnitude of the Charges (\( q_1 \) and \( q_2 \))**: The force is directly proportional to the product of the charges. This means that if the magnitudes of either or both charges increase, the force between them also increases proportionally. For instance, doubling one of the charges will double the force.

2. **Distance Between the Charges (\( r \))**: The force is inversely proportional to the square of the distance. This means that as the distance increases, the force decreases rapidly. Specifically, if the distance is doubled, the force decreases to a quarter of its original value, as it’s divided by \( 2^2 = 4 \).

### Conclusion
The **distance between the charges** has a more significant effect on the force than the magnitudes of the charges. This is because the force changes with the square of the distance, making it a quadratic effect, whereas the force changes linearly with the charge magnitudes. Therefore, a small change in distance can have a large impact on the force, while the same proportional change in charge magnitude would have a lesser effect.

Would you like more detailed examples or have further questions?

Here are some related questions to explore:
1. How would the force change if both charges were doubled but the distance remained the same?
2. What happens to the force if one charge is halved and the distance is doubled?
3. How does the force compare if the distance is halved instead of the charges being doubled?
4. Can Coulomb’s Law be applied if the charges are not point charges?
5. How does the medium between charges affect the force, considering Coulomb’s Law?

**Tip**: When dealing with inverse-square laws, always consider that small changes in distance can drastically affect the result due to the squared relationship.

What matters more: the magnitude of the charges or the distance between charges? Use Coulomb's Law to support your claim.
