State and explain coulomb's law in electrostatics
Answers
Answer:
Coulomb's Law: The Electrostatic Force of interaction between two static point electric charges is directly proportional to the product of the charges, inversely proportional to the source of the distance between them and acts along the straight line joining the two charges

Explanation:
Coulomb's law in electrostatic states that a charge at rest q
1
applies a force F on the other charge q
2
, also at rest, which are separated by a distance r such that the force is directly proportional to the product of both charges and inversely proportional to the square of the distance between them.
∴ F∝q

q

and F∝

Thus we get F∝
