Coulomb's law describes the electrostatic force between charged objects. It states that the magnitude of the electrostatic force \( F \) between two point charges \( q_1 \) and \( q_2 \) is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance \( r \) between them. Mathematically, it can be expressed as:
\[
F = k \frac{|q_1 q_2|}{r^2}
\]
Where:
- \( F \) is the magnitude of the force between the charges,
- \( k \) is Coulomb's constant (approximately \( 8.99 \times 10^9 \, \text{N m}^2/\text{C}^2 \)),
- \( |q_1| \) and \( |q_2| \) are the magnitudes of the charges,
- \( r \) is the distance between the centers of the two charges.
The force is attractive if the charges are of opposite signs and repulsive if they are of the same sign.
