State Coulomb's law of force between two electric charges
  • 1 answers

Yogita Ingle 4 years, 3 months ago

 

Coulomb's law in electrostatic states that a charge at rest q1​ applies a force F on the other charge q2​, 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∝ q1​q2​ and F ∝ 1/ r21

Thus we get F ∝ q1​q2​​/r2

⟹ F = kq1​q2​​/r2 where k= 1/4πϵo​​
