If two point charges of charge q1 and q2 are placed at distance d, then the force between them is proportional to:
Correct answer: D. q1 x q2
- A. q1 + q2
- B. q1 - q2
- C. q1/q2
- D. q1 x q2
Explanation
Coulomb's Law states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to square of the distance between them. Hence the Option D is the correct answer for this question.

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.
