Solution
Correct Answer:
Product of charges
- Coulomb's Law Statement: The magnitude of the electrostatic force between two point charges is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.
- Mathematical Expression: F=kr2q1q2.
- Variables:
- q1,q2: Magnitudes of the two charges.
- r: Separation distance between charge centers.
- k: Electrostatic constant (k≈9×109 N m2/C2).
- Conclusion: According to the numerator of the formula, the force is directly proportional to the product of the charges.
