Optimizing Coulomb's Law: Finding Maximum and Minimum Charges

In summary, the conversation is about a person seeking help with a homework question related to charged objects and the force between them. The forum has rules in place that require the person to show evidence of their own attempt before receiving help. The person is asked to start a new thread with the provided template if they want to continue pursuing the question.

Hi, I'm having trouble figuring out one of my homework questions. It says
" The total charge on two charged objects is Q. What must the charges on each of them be, in order that the force between them is (a) maximum and (b) minimum.Thanks guys.

Hi deldel, one of the rules of Physics Forums is that we're not allowed to offer help with homework questions until you provide evidence of your attempt to find the answer yourself. That's why the template is provided for homework questions.

Hi deldel, Welcome to Physics Forums!

I'm closing this thread as it lacks the template and an attempt at solution.

@deldel , please start a new thread and use the template provided if you would like to pursue this question further.

Thanks for participating in Physics Forums!
 

1. What is Coulomb's law?

Coulomb's law is a fundamental law in physics that describes the electrostatic force between two charged particles. It states that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

2. Who discovered Coulomb's law?

Coulomb's law was discovered by French physicist Charles-Augustin de Coulomb in 1785. He conducted experiments with charged spheres and measured the force between them to develop this law.

3. What is the SI unit of electric charge in Coulomb's law?

The SI unit of electric charge is the Coulomb, named after the scientist who discovered Coulomb's law. It is represented by the symbol "C".

4. How does Coulomb's law relate to the concept of electric fields?

Coulomb's law is used to calculate the electric field strength at a point due to a charged particle. The electric field is a vector quantity that describes the direction and magnitude of the force experienced by another charged particle at that point.

5. Can Coulomb's law be applied to all types of charges?

Yes, Coulomb's law can be applied to all types of charges, including positive and negative charges. It also applies to point charges, which are particles with negligible size and shape, and to larger objects as long as the distance between them is much greater than their size.
