write all the limitations of Coulomb's law.
Answers
Hello....
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:
It is the law that the force (attraction/repulsion) between two charges is equal to the product of their charges and inversely proportional to the square of distance between them.
LIMITATIONS OF COULOMB'S LAW:
1)Applicable only in cases when inverse law works.
2)Applicable For Point Charges at Rest
3)It is Difficult to apply Coulomb's Law,when charges are in arbitrary shape.
In Short: F ∝ q1q2/d2
where,
1)ε is absolute permittivity,
2)K or εr is the relative permittivity or specific inductive capacity
3)ε0 is the permittivity of free space.
4)K or εr is also called a dielectric constant of the medium in which the two charges are placed.
History of Coulomb’s Law:
A French physicist Charles Augustin de Coulomb in 1785 coined a tangible relationship in mathematical form between two bodies that have been electrically charged. He published an equation for the force causing the bodies to attract or repel each other which is known as Coulomb’s law or Coulomb’s inverse-square law.
