Question:--
What is Coulomb’s Law?
Answer:--
According to Coulomb’s law, the force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. It acts along the line joining the two charges considered to be point charges.

1) What is 1 Coulomb of Charge?
Answer:--
A coulomb is that charge which repels an equal charge of the same sign with a force of 9×109 N when the charges are one meter apart in a vacuum. Coulomb force is the conservative mutual and internal force.
The value of εo is 8.86 × 10-12 C2/Nm2 (or) 8.86 × 10-12 Fm–1.
2) What type of law is Coulomb's law said to be ELECTRIC FIELDS?
Answer:--
Coulomb's law states that the force F between two point charges, Q1 and Q2, in a vacuum is proportional to their product and inversely proportional to the square of their distance apart r.
3) How do you derive Coulomb's law?
Answer:--
Coulomb's law states that the electrostatic force between any two points is directly proportional to the product of the magnitude of these charges and inversely proportional to the square of the distance between them.
4) Who invented Coulomb law?
Answer:--
The law was first discovered in 1785 by French physicist Charles-Augustin de Coulomb, hence the name. Coulomb's law was essential to the development of the theory of electromagnetism, maybe even its starting point, as it made it possible to discuss the quantity of electric charge in a meaningful way.
5) How was Coulomb's law discovered?
Answer:--
Charles Augustin Coulomb (top)
used a calibrated torsion balance (bottom)
to measure the force between electric charges. Around 600 BC, the Greek philosopher Thales wrote that when he rubbed pieces of amber with fur,
the amber attracted bits of straw and other small objects.
Answer:
The law is applicable only for the point charges at rest. Coulomb's Law can be only applied in those cases where the inverse square law is obeyed. It is difficult to implement Coulomb's law where charges are in arbitrary shape because in such cases we cannot determine the distance' between the charges.
