Coulomb's law is only applicable for _.
Correct answer: C. Point charges
- A. Big charges
- B. Small charges
- C. Point charges
- D. Any charges
Explanation
According to Physics Sindh Textbook pg 40.It clearly states "..... two static point charges....." , i.e the charge is at a single point in space.

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.
