Question

What is coulomb's law of electrostatics

Answer 1

Coulomb's law in electrostatic

The force of attraction or repulsion b/w two point charges at rest is directly proportional to the product of the magnitude of the charges and inversely proportional to the square of the distance separating them.

Let two charges q1 anf q2 are kept at a distance r apart. If the effectivene force acting b/w them be F,then according to Coulomb's lae of electrostatic, F directly proportional to q1q2 and F inversely proportional to r2.

Answer 2

coloumb's law of electrostatics state that the force of attraction between two point charges are directly proportional to the product of the charges and inversely proportional to the square of the distance of separation between them.
