state coulombs law
Coulomb's law is a fundamental principle in physics that describes the force between two charged particles. It states that the force between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. Mathematically, Coulomb's law can be expressed as:
F = k * (q1 * q2) / r^2
Where:
- F is the magnitude of the electrostatic force between the charges,
- k is the Coulomb constant (k ≈ 8.99 x 10^9 N m^2/C^2),
- q1 and q2 represent the charges of the particles, and
- r is the distance between them.
To use Coulomb's law, you need to know the charges of the particles (q1 and q2) and the distance (r) between them. Simply plug these values into the equation to calculate the force (F) between the charges.
Note that Coulomb's law assumes the charges are point charges (infinitely small), and it applies to electrostatic forces when the charges are at rest.
