Final answer:
Coulomb's law describes the electrostatic force between charged objects, while Newton's law of gravity describes the force of attraction between objects with mass. The two laws differ in terms of the strength of the force and the types of charges and masses involved.
Step-by-step explanation:
Coulomb's law describes the electrostatic force between charged objects, while Newton's law of gravity describes the force of attraction between objects with mass.
The two laws differ in two main aspects:
- The gravitational constant G is much smaller than the constant k in Coulomb's law, which means that the gravitational force between objects is much weaker than the electrostatic force.
- While there is only one type of mass, there are two types of electric charge, so the electrostatic force can be attractive or repulsive, whereas gravity is always attractive.
