In summary, Coulomb's Law is a fundamental law in physics that describes the force between two charged particles. It was discovered by French physicist Charles-Augustin de Coulomb in 1785 and is represented by the formula F = k(q1q2)/d^2. Coulomb's Law is closely related to electric fields and has many real-life applications in electronics, chemistry, and everyday life.

how columb knew that the force between the charge is inverse square law in nature

With careful measurements with the use of a torsion balance () he saw it was ~1/r². Today we've tested that the power of r is exactly 2 to about 15 decimals or so.

FAQ: What evidence supports the inverse square law in Coulomb's law?

What is Coulomb's Law?

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.

Who discovered Coulomb's Law?

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.

What is the formula for Coulomb's Law?

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.

How does Coulomb's Law relate to electric fields?

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.

What are some real-life applications of Coulomb's Law?

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.
