Coulomb's Law 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 them.
How is Coulomb's Law formula expressed?
The formula is F = k * (|q1 * q2| / r^2), where F is force, q1 and q2 are the magnitudes of the charges, r is the distance between charges, and k is Coulomb's constant.
What units are used in Coulomb's Law?
In Coulomb's Law, force is measured in newtons, charge in coulombs, distance in meters, and the constant k in Nm²/C².
What is an application of Coulomb's Law in everyday life?
