Question

State coulomb's law in electrostatics. write the corresponding formula for magnitude of coulomb's force​

Answer 1

Answer:

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

1

q

and F∝

Thus we get F∝
