You will get to learn about Coulombs law by observing real-life applications and performing an experiment to determine the factors that affect the force between two charged particles.
After completing this tutorial, you will be able to complete the following:
What happens if the distance between two charged particles remains constant, but the quantity of charge increases?
~ When the distance between two charged particles remains constant, but the quantity of charge on the particles increases, the force between these charges also increases in proportion.
What is the formula that represents Coulomb's law?
What does the k represent in Coulomb's formula?
~ The k represents Coulomb's constant, and it is equal to 9 x 109 Nm2/C2.
What are the variables that affect Coulomb's force?
~ The variables that affect Coulomb's force are the distance between the charges and the amount of charge. The repulsion-attraction force is directly proportional to the product of the charges, and inversely proportional to the square of the distance between them. The force also depends on the dielectric constants of any media between the charges.
