Two point charges attract or repel each other with a force which is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.
Where, [In SI, when the two charges are located in vacuum]
− Absolute permittivity of free space = 8.854 × 10−12 C2 N−1 m−2

Electric force and its application?
an attraction or repulsion between electrically charged that opperates according to the law of electric forces charges and Coulomb's law of electric force
Is lightning a magnetic and electric force?
yes it is
What is a combination of electricity and magnets?
It is the electromagnetic force that speaks to the electric and magnetic forces. They (electric force and magnetic force) are one force in the eyes of the physicist. Use the link below for more information.
How does the strength of the electric field vary with the distance for the positive point charge?
It is known as Coulomb's law and is the equivalent in electrostatics of the Newton's law for gravity. This is a law falling in the "inverse square" category, meaning there is a relationship of the form 1 / (square n). When the distance is multiplied by n, the field is divided by square n, e.g. if the distance double, the field is divided by 4.The exact formulation of Coulomb's law is:E = 1 / (4 pi . epsilon0) . q / r2E being the magnitude of the field, which is what you want to know. Unit is V/m.epsillon0 being the electric constant (vacuum permittivity). Unit is C/V/mq being the charge of the particle creating the field. Unit is Coulomb.r being the distance from the charge. Unit is m.The "inverse square" factor is q / r2Coulomb's law is a special case of Gauss's law which is turn is included in the Maxwell's set of equations. It turns out that, in magnetism there are only two guys in charge... Maxwell and Lorentz. Kind of monopoly.
Who developed a unit of electric potential and electromotive force?
albert Einstein
How do you calculate electrostatic force?
coulombs law
What does coulombs law find?
The force between two charged particles.
How is coulombs law the same as newtons law how are the?
Both have the concept of variation of force inversely with the square of the distance. But in case of coulomb we have electric charges and in case of newton's gravitation law we have masses. Coulomb's force can be either attractive and repulsive where as Newton's is only attractive
How is coulombs law the same as newtons law how are the laws different?
Both have the concept of variation of force inversely with the square of the distance. But in case of coulomb we have electric charges and in case of newton's gravitation law we have masses. Coulomb's force can be either attractive and repulsive where as Newton's is only attractive
What are the limitations coulombs law?
Limitations of coulombs law
What is Coulombs law equation?
Coulombs Law symbol equation is F=Kc*q1*q2/r² F= force between the 2 Electric Charges. Kc=Coulomb's constant = 8.9876 x 10^9 N m^2 C^-2 q1 and q2= Scale of each eletric charge r= Distance between the 2 electric charges
According to Coulombs Law how does distance affect the electric force?
Electric force can act at a distance, but is stronger when objects are closer. the electric force is larger the closer the two objects are The electric force varies with the distance between the charges. The closer they are, the stronger the force. The farther apart they are, the weaker the force.
What is the force that causes electrons to move in a conductor?
A charge is transferred (coulombs) and this amounts to an electric current (amps)
How is newtons law different from coulombs law?
Both have the concept of variation of force inversely with the square of the distance. But in case of coulomb we have electric charges and in case of newton's gravitation law we have masses. Coulomb's force can be either attractive and repulsive where as Newton's is only attractive
Is coulombs law a universal law?
No
Electric force and its application?
an attraction or repulsion between electrically charged that opperates according to the law of electric forces charges and Coulomb's law of electric force
How is coulombs law different from newton law?
Newtons law has to due with mass and ATTRACTION only Coulombs law has to due with charge and ATTRACTION AND REPULSION
