Coulomb's law is a fundamental law of physics that explains the electrostatic interaction between two charged particles. It states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
To calculate the force between two charged particles, you can use the formula F = k(q1q2)/r^2, where F is the force in Newtons, k is the Coulomb's constant (8.99 x 10^9 Nm^2/C^2), q1 and q2 are the charges of the two particles in Coulombs, and r is the distance between the two particles in meters.
The force between two charged particles is inversely proportional to the square of the distance between them. This means that as the distance between the particles increases, the force between them decreases. Similarly, as the distance decreases, the force increases.
Yes, Coulomb's law can be used to calculate the force between non-point charges, such as charged spheres or cylinders. In this case, the distance between the charges is measured from the center of one charge to the surface of the other charge.
Coulomb's law and Newton's law of gravitation are both inverse-square laws, meaning that the force between two particles is inversely proportional to the square of the distance between them. However, Coulomb's law applies to electrostatic interactions between charged particles, while Newton's law of gravitation applies to gravitational interactions between massive objects.
