If two point charges of charge q1 and q2 are placed at distance d. The force between them is proportional to:
Correct answer: D. 1/d2
- A. d
- B. d2
- C. 1/d
- D. 1/d2
Explanation
Force between two charges q1 and q2 separated by a distance r is proportional to q1 x q2 / r2

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.
