Which one of the following statements is true?
Correct answer: C. gravitational force is much weaker than electrostatic forced.
- A. electrostatic force obeys inverse square law while gravitational force does not
- B. Both gravitational force and electrostatic force are repulsive in nature
- C. gravitational force is much weaker than electrostatic forced.
- D. Both electrostatic force and gravitational force don't obey inverse square law
Explanation
Gravitational force is indeed much weaker compared to electrostatic force.

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.
