Hello, reader, you are very warmly welcome again into the world of Physics on our website. We are representing a very precious article What is electrostatic force, that comes under the branch of physics, electrostatic. This force is also known as Coulomb’s law force because it is based on Coulomb’s law given by the scientist Coulomb. This is a very common phenomenon we observed in our day-to-day life very sparingly. So I think this article is going to be very important for all types of people, they can be science students or normal people not related to the science stream.
From the exam point of view this article, What is Electrostatic Force, is going to be the most important topic for all types of examinations. It may be JEE or NEET or any board exam. We will discuss some important types of questions such as What is Electrostatic Force, electrostatic force, electrostatic force formula, what is an electrostatic force, electrostatic force equation, etc. These all questions will define in very understandable language. So I request you to read this whole article from the first paragraph to the and paragraph. Let us start our today’s important article (What is electrostatic force) without consuming much time.
The Electrostatic Force (Statement)
The electrostatic force is the very fundamental force that exists in our universe. There are mainly fundamental forces known in our universe. the name of the fundamental of electromagnetic force beak nuclear force strong nuclear force and gravitational force. according to the physics law, the electrostatic force lies under the category of electromagnetic force.
The origin of the electrostatic force (What is electrostatic force) is due to two charged bodies. This force may be attractive or maybe repulsive between the charged bodies. Attraction and repulsion depend on the nature of the charge possess by the charged bodies.
If there are two bodies that have the same charge let’s suppose they both have a positive charge, then when we brought the charged bodies close to each other, The bodies feel the force of repulsion. And If there are two bodies that have the same charge let’s suppose they both have the negative charge, then when we brought the charged bodies close to each other, The bodies again feel the force of repulsion. If there are two bodies that have the opposite charge. let’s suppose one has a positive charge and another has a negative charge, then when we brought the charged bodies close to each other, The bodies feel the force of attraction.
From the observation, We can easily say that the same charge bodies always repel each other, and opposite charge bodies always attract each other.
Coulomb’s Law (Electrostatic Force Law Equation)
This law is given by the great scientist Coulomb. This is also known as the electrostatic force law. According to this law-
- The force of attraction or the repulsion between two charged bodies is in direct proportion to the product of the value of the charges.
- The force of attraction or the repulsion between two charged bodies is in inverse proportion to the square of the separation between the two charge bodies.
Let’s suppose there are two charges that have the magnitude q1 and q2 placed at a separation of r from each other, then to calculate the electrostatic force, work between these bodies is given by the Electrostatic force formula-
FE=kq1q2 / r2
- k is a constant. Its value in SI units (International system of units) is k = 9 × 109 Nm2C-2
- Generally this constant is written in this way: k = 1/4πε0
- r is the separation.
- where ε0 is known as the permittivity constant Of the medium which has a numerical value equal to εo = 8.85 × 10−12 C2 /Nm2
Examples of the Electrostatic Force
There are many examples of the electrostatic force in our daily life and in the natural world be had discussing some examples-
- A very familiar example of the electrostatic force is an attraction between the electrons and the protons in any atom. This electrostatic force inside any atom is responsible for the stability of that atom as well as the matter.
- Another common example of the law of electrostatic force we observed was when any person’s hair was attracted toward a balloon after rubbing the balloon on his clothes. This phenomenon happens due to the transfer of electrons from the cloth to the balloons or the balloon to the cloth. This results in the balloon and the hair possessing opposite charges that attract each other.
- Another common example is the feeling of shock you get by touching a doorknob after walking on any carpet. This phenomenon also happens due to the transfer of electrons, where the excess electrons on your body are displaced or transferred to the doorknob, thus resulting in a short-range current flow and a shock you feel of a low magnitude.
- The attraction between the negative terminals and positive terminals of a battery. This attraction happens by the electrostatic force works between the opposite charges. and this is the main cause of the generation of electrical power by the battery.
The final words of today’s article what is electrostatic force, are that in this article we have told about money topics under the electrostatic force definition. We also discussed very important types of questions that are asked generally in different types of comparative examinations. these questions are in the form of MCQs or like electrostatic force definition, calculating electrostatic force, electrostatic force examples, how to calculate electrostatic force, define electrostatic force (What is electrostatic force), electrostatic force meaning, etc. For any doubts or suggestions, you can ask your doubts in the comments section box. We are glad to resolve your query as soon as possible.
