Here is your answer if u get the concept then mark this as brainliest.

Answer 2

Answer:

Explanation:

Coulomb's law:

Coulomb's law states that the force of attraction or repulsion between two charged bodies is inversely proportional to the square of the distance between them and directly proportional to the product of their charges. It operates on the segment connecting the two charges regarded as point charges.

History of Coulomb's law:

In $1785$, French scientist Charles Augustin de Coulomb developed a concrete mathematical relationship between two electrically charged things. He produced an equation for the force, often known as Coulomb's law or Coulomb's inverse-square law, that causes the bodies to attract or repel one another.

From Coulomb's law, the forces exerted by one on the other are equal and opposite direction that is $| F12| = |-F21|$

Thus the required ratio will be $1:1$.
