how columb knew that the force between the charge is inverse square law in nature
Coulomb's Law is a fundamental law in physics that describes the force of attraction or repulsion between two charged particles. It states that the force is directly proportional to the product of the two charges and inversely proportional to the square of the distance between them.
Coulomb's Law was discovered by French physicist Charles-Augustin de Coulomb in 1785. He conducted experiments with charged objects and found that the force between them followed a predictable pattern.
The formula for Coulomb's Law is F = k(q1q2)/d^2, where F is the force, k is the Coulomb constant (8.99 x 10^9 Nm^2/C^2), q1 and q2 are the charges of the two particles, and d is the distance between them.
Coulomb's Law is closely related to electric fields. The force between two charged particles is the result of the electric field created by one particle acting on the other. The electric field is a vector quantity that describes the direction and strength of the force at any point in space.
Coulomb's Law has many practical applications, such as calculating the force between charged particles in electronics, understanding the behavior of atoms and molecules, and designing devices like electrostatic precipitators used in air pollution control. It is also fundamental to our understanding of electricity and magnetism in everyday life.
