The Coulomb's law states:
Correct answer: B. Force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
- A. Force between two point charges is inversely proportional to the product of the charges and directly proportional to the square of the distance between them.
- B. Force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
- C. Force between two point charges is directly proportional to the sum of the charges and inversely proportional to the square of the distance between them.
- D. Force between two point charges is directly proportional to the product of the charges and to the square of the distance between them.
Explanation
Coulomb's law describes the electrostatic interaction between charged particles. It states that the force (F) between two point charges (q1 and π2) is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance (r) between them

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.
