Coulomb's Law

The force between charged bodies is no contact force. It exists over a length, and all electrical interaction has a force embedded in it. The charges and distance between the charged bodies are the factors that determine the power and influence of the force. The same force exists, whether it’s a plastic comb attracting paper pieces or two electrons repelling each other.

What Is Coulomb’s Law?

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.

What Is 1 Coulomb of Charge?

A Coulomb is a charge which repels an equal charge of the same sign with a force of 9×109 N when the charges are one metre apart in a vacuum. Coulomb force is the conservative mutual and internal force.

The value of εo is 8.86 × 10-12 C2/Nm2 

Note: Coulomb force is true only for static charges.

Coulomb’s Law – Conditions for Stability

If q is slightly displaced towards A, FA increases in magnitude while FB decreases in magnitude. Now, the net force on q is toward A, so it will not return to its original position. So for axial displacement, the equilibrium is unstable.

If q is displaced perpendicular to AB, the force FA and FB bring the charge to its original position. So, for perpendicular displacement, the equilibrium is stable.

Key Points on Coulomb’s Law

1. If the force between two charges in two different media is the same for different separations,  then Kr2 = constant or K1r12 = K2r2

1140122=

2. If the force between two charges separated by a distance ‘r0’ in a vacuum is the same as the force between the same charges separated by a distance ‘r’ in a medium, then from Coulomb’s law, Kr2 = r02

3. Between two electrons separated by a certain distance: Electrical force/Gravitational force = 1042

4. Between two protons separated by a certain distance: Electrical force/Gravitational force = 1036

5. Between a proton and an electron separated by a certain distance: Electrical force/Gravitational force = 1039

6. The relationship between the velocity of light, the permeability of free space and the permittivity of free space is given by the expression c = 1 / √ (μoεo )

=12 ()()=1

Limitations of Coulomb’s Law

  • The law is applicable only for the point charges at rest.
  • Coulomb’s law can only be applied in those cases where the inverse square law is obeyed.
  • It is difficult to implement Coulomb’s law where charges are in arbitrary shape because, in such cases, we cannot determine the distance between the charges.
  • The law can’t be used directly to calculate the charge on big planets.

 

Frequently Asked Questions on Coulomb’s Law

Q1

State Coulomb’s inverse-square law in electrostatics.

The electrostatic force of attraction or repulsion between two stationary point charges is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.

Q2

What are the limitations of Coulomb’s law?

Coulomb’s law holds good for stationary point charges.
Coulomb’s law is not universal, as it depends on the properties of the intervening medium.

Q3

Is the electrostatic force between two point charges a central force?

Yes. The electrostatic force between two point charges always acts along the line joining the two charges. Hence, it is a central force.

Q4

What is one Coulomb of charge?

One Coulomb of charge is that charge which, when placed at rest in a vacuum at a distance of one metre from an equal and similar stationary charge, repels it and is repelled by it with a force of 9 x 109 Newton.

In the  CBSE  curriculum, understanding the concept of electric charge and its various types by ANAND CLASSES is of utmost importance.    MODERN ELECTRON THEORY   From the study of atomic structure, we know that an atom consists of a central part called nucleus and around the nucleus (called extra-nucleus) there are a number of electrons revolving in different paths or orbits.  The nucleus contains protons and neutrons. A proton is a positively charged particle while a neutron has no charge. Therefore, the nucleus of an atom bears a positive charge. An Electron is a negatively charged particle having negative charge equal to the positive charge on a proton. Normally, the number of electrons is equal to the number of protons in an atom. Therefore, an atom is neutral as a whole; the negative charge on electrons cancelling the positive charge on protons. This leads to the conclusion that under ordinary conditions, a body is neutral, i.e. it exhibits no charge.  WHAT IS AN ELECTRIC CHARGE

What Is a Capacitor? A capacitor is a two-terminal electrical device that can store energy in the form of an electric charge. It consists of two electrical conductors that are separated by a distance.  The space between the conductors may be filled by vacuum or with an insulating material known as a dielectric. The ability of the capacitor to store charges is known as capacitance. Capacitors store energy by holding apart pairs of opposite charges. The simplest design for a capacitor is a parallel plate, which consists of two metal plates with a gap between them. But, different types of capacitors are manufactured in many forms, styles, lengths, girths, and materials. How Does a Capacitor Work? The most basic structure of a capacitor is the parallel plate capacitor. It consists of two parallel plates separated by a dielectric. When we connect a DC voltage source across the capacitor, one plate is connected to the positive end (plate I) and the other to the negative end (plate II). When
