Which one of the following is NOT a feature of electric forces?
Correct answer: B. They act on masses
- A. They act on charges
- B. They act on masses
- C. They can be attractive.
- D. They can be repulsive
Explanation
Option B is Incorrect because electric forces act on charge, not mass (gravitational forces act on mass). And it is not a feature of electric forces.

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.
