What is coloumbs law ??
Give its equation
Answers
Answer:
Coulomb's law, or Coulomb's inverse-square law, is an experimental law of physics that quantifies the amount of force between two stationary, electrically charged particles. The electric force between charged bodies at rest is conventionally called electrostatic force or Coulomb force.
Explanation:
According to Coulomb’s law, the force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. It acts along the line joining the two charges considered to be point charges.
Coulomb’s Law Formula: F ∝ q1q2/d2
where,
ε is absolute permittivity,
K or εr is the relative permittivity or specific inductive capacity
ε0 is the permittivity of free space.
K or εr is also called a dielectric constant of the medium in which the two charges are placed.
Answer:
The magnitude of the elastrostatic force of attraction or repulsion between two points charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them.
