_ law states that the magnitude of the force between 2-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.
Correct answer: C. Coulomb's law
- A. Ohm's law
- B. Gauss law
- C. Coulomb's law
- D. Lenz law
Explanation
Coulomb's law states that the magnitude of the electrostatic force (F) between two point charges (q1 and q2) is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance (r) between them:F ∝ (q1 × q2) / r²orF = k × (q1 × q2) / r²where k is Coulomb's constant.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
