coulomb's law
There is a law about the static electric force between electric charges, propounded by a Franciscan scientist named Coulomb in the 1790s. This law served as the basis for the development of the theory of electromagnetism. This law is in scalar form. Or can be expressed in vector form. In scalar form, this rule is as follows. The value of the electrostatic force between two point charges is proportional to the product of those charges. And the square of the distance between those charges. is inversely proportional
Let two charges q1 and q2 be at a distance r from each other. so the force between them F \large \frac {q_1q_2}{r^2} r 2 q 1 q 2 (where q1 is the first charge, q2 is the second charge) F = k\large \frac {q_1q_2}{r^2} r 2 q 1 q 2 Here k is a constant. Which is called dielectric point. Its value \frac {1}{4πԐ_0} 4 0 1 it happens. Its unit is newton-meter2/coulomb2. now what
Coulomb's law formula
The force between two stationary point charges is directly proportional to the quantities of the two charges and inversely proportional to the distance between them. This is called Coulomb's law.
Coulomb’s law formula-F=1/4πԐ×q1q2/r 2
How are charges generated in the matter?
When two objects are rubbed, the atom of one object goes to the atom of the other object. In this type of distribution of electrons, there is a shortage of electrons in the object, giving electrons. Meaning that money gets charged.
And due to the arrival of electrons on the second object, it becomes negatively charged. Thus charges are generated on both objects.
Significance of Coulomb's Law
1-the forces that act between the nucleus and the electrons of an atom
2-Coulomb's force is true for very long distances to short distances(10^-14m). The force becomes very high over short distances whose value does not depend on the nature of the charges on the particles. This force is called nuclear force.
Bio-Savart's law
Bio Saver's law is an equation under electromagnetism that gives the value of the magnetic field B produced by an electric current at a point. Gives the value of the vector quantity B. The vector quantity B depends on the magnitude, direction, length, and distance of the point. This law is valid in a stationary magnetic state. And the value of B obtained from it corresponds to the magnetic field obtained from Ampere's law and Gauss's law. This law is used to calculate the magnetic field produced by a steady electric current. And this rule was formulated in the year 1920. B = is the value of the magnetic field.
Difference between Bio-Savart's law and Coulomb's law
1-Coulomb's law works in both vector and scalar forms.
Whereas Bio's law gives only the value of the vector quantity
2-Coulomb's law is the basis for the development of the theory of electromagnetism.
and Bio's law under electromagnetism is the equation
3-Coulomb's law led to the development of the theory of electromagnetism
And Bio's law tells the value of the magnetic field
