What is the primary difference between Coulomb's law and Newton's law of gravitation?.
- A.Coulomb's law applies to electric charges, while Newton's law applies to masses.
- B.Coulomb's law is only applicable in a vacuum, while Newton's law can apply in any medium.
- C.Coulomb's law describes attractive forces only, while Newton's law describes both attractive and repulsive forces.
- D.Coulomb's law is based on point charges, while Newton's law is based on distributed masses.
Model answer
What a good answer should say
- Coulomb's law applies to electric charges, while Newton's law applies to masses.
Explanation
Why this works
Coulomb's law defines the force between two charged objects, while Newton's law of gravitation defines the force between two masses. The key difference is that Coulomb's law applies to electric charges, which can be either positive or negative, while Newton's law applies to masses, which always attract each other.
Coulomb's law is applicable in scenarios involving electric fields and charges, while Newton's law is used in gravitational contexts. Thus, Coulomb's law is relevant for understanding interactions in electric fields, whereas Newton's law is essential for gravitational interactions.
