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.
What is the relationship between the direction of an electric field and the direction of the force that the field would exert?
The direction of an electric field is the direction of the force that the field would exert on a proton.. ___ The relationship of the direction of an electric field and the direction of force that the field would exert are the same. Let's look. Consider the humble electron, the carrier of the negative electrostatic force. The electric field around the electron can be said to "stand out around the electron" equally and in all directions. We need to form a mental picture, so let's try to do that. Think of the electron as a little ball floating in space. Now picture it with long, thin "needles" sticking out of it in all directions. Each needle is a line of electric force, and its direction is "out" or "away" from the center of the ball that is the electron. Got that picture? The negative electric force about any elementary charged particle is just like the picture we have of the electron and its electric field. The force acts "out" like that. In the case of a positively charged particle, the same model applies, except that positive and negative forces attract while two negative or two positive forces repel each other, just as is set down in the law of electrostatics. Simple and easy. Note that electric and magnetic fields have a little different way of interacting, and this question doesn't cover that.
How do you calculate electrostatic force?
coulombs law
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
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 unit of coulombs force?
The unit of force in the Coulomb's law equation is the Newton (N).
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
What is the force that causes electrons to move in a conductor?
The force that causes electrons to move in a conductor is an electric field created by a voltage difference across the conductor. This electric field exerts a force on the negatively charged electrons, causing them to flow in the direction of the electric field.
Ball A has a charge of 3 Coulombs Ball B has a charge of 5 Coulombs What is the net electric charge?
The net electric charge is the sum of the charges of ball A and ball B. So, the net electric charge is 8 Coulombs.
How is newtons law different from coulombs law?
Newton's law of universal gravitation describes the force of gravitation between two masses, while Coulomb's law describes the force of electrostatic interaction between two charged particles. Newton's law involves the force of attraction between masses and is always attractive, whereas Coulomb's law involves the force of interaction between charges and can be attractive or repulsive depending on the charges. Additionally, the mathematical forms of the two laws are different, with Newton's law involving gravitational constant G and Coulomb's law involving electric constant k.
