Question

describe in detail coulombs law

Answer 1

Coulomb's Law is a law of physics that describes the interaction between electrically charged objects. ... This law states that the electrostatic force between two objects is proportional to the product of the charge of each of the objects and inversely proportional to the square of the distance between these two objects. A statement in physics: the force of attraction or repulsion acting along a straight line between two electric charges is directly proportional to the product of the charges and inversely to the square of the distance between them.

Answer 2

$\boxed{\boxed{\huge{\bf{Answer}}}}$

The force between two small charged particles is directly proportional to the product of the charges and inversely proportional to the square of distance between them.

It also tells us that opposite charges attract and like charges repel.

The SI unit of charge is coulomb which is denoted by the letter C. We can define this unit of charge as follows : One coulomb is that quantity of electric charge which exerts a Force of

9 * 10^{9}9∗10

9

Newton on an equal charge placed at a distance of 1 metre from it.

The SI unit of charge 'coulomb' (C) is equivalent to the charge contained in

6.25 * 10^{18}6.25∗10

18

electrons.
