Coulomb's Law: The distance between two charged spheres

In summary, Coulomb's Law is a fundamental law of electrostatics that states the force of attraction or repulsion between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. This means that as the distance between two charged objects increases, the electric force between them decreases. The formula for Coulomb's Law is F = k * (q1 * q2)/r^2, and it is similar to Newton's Law of Universal Gravitation, which describes the force of attraction between two masses. However, Coulomb's Law applies specifically to electric charges, while Newton's Law applies to masses.

Homework Statement
“If the distance between two charged spheres decreases, then the force on the sphere _______, because____.”
Relevant Equations
Fe= q1q2/ r^2
The force of the sphere increases because according to Coulomb's force increases as the distance decreases.

I'm not sure if this is correct.

Can you verify your conclusion? Suppose the distance were reduced to half its original value. By what factor would the force change?
 

What is Coulomb's Law?

Coulomb's Law is a fundamental law of electrostatics that describes the force between two charged objects. It states that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between the charges.

How does distance affect the force between two charged spheres?

The force between two charged spheres is inversely proportional to the square of the distance between them. This means that as the distance between the spheres increases, the force decreases.

How is Coulomb's Law related to Newton's Law of Universal Gravitation?

Coulomb's Law and Newton's Law of Universal Gravitation both describe the force between two objects. However, Coulomb's Law applies to electrically charged objects while Newton's Law applies to objects with mass.

Can Coulomb's Law be used to calculate the force between more than two charged spheres?

Yes, Coulomb's Law can be used to calculate the force between any number of charged spheres. The force between each pair of spheres can be calculated separately and then added together to find the total force.

What is the unit of measurement for the force in Coulomb's Law?

The unit of measurement for force in Coulomb's Law is Newtons (N). This is the same unit of measurement for force in Newton's Law of Universal Gravitation.
