"The magnitude of the electrostatic force between two point charges is directly proportional to the product of the magnitude of the charges and inversely proportional to the square of the distance between them." This is known as:
Correct answer: E. Coulomb's Law
- A. Gauss's Law
- B. Ohm's law
- C. Faraday's law
- D. Newton's Law
- E. Coulomb's Law
Explanation
The above statement is the definition of Coulomb's Law which states that the electrostatic force(F) between two point charges is directly proportional to the product of the magnitude of charges (Qq) and inversely proportional to the square of distance(r2) between them. Mathematically: F=kQq/r^2where k is the constant of proportionality.So option E is correct.

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.
