What causes electrically charged objects either to attract or repel one another?

Charges that are the same (positive and positive or negative and negative) push each other away, or repel. Charges that are opposite (positive and negative) draw one another together, or attract. An object with an excess of positive charges attracts negative charges until the numbers are equal again.

What determines whether charges attract or repel?

In Coulomb’s law, however, the magnitude and sign of the electric force are determined by the electric charge, rather than the mass, of an object. … Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge.

Why do like charges repel each other?

Whenever two like charges are placed near each other, they start exchanging a virtual photon amongst themselves, which transfers the momentum between them, and thus they appear to repel each other.

What is the effect an electric charge has on other charges in the space around it?

Electric Field The effect an electric charge has on other charges in the space around it.
Static Electricity The study of the behavior of electric charges, including how charge is transferred between objects.

How does the magnitude of the electrical force between a pair of charged particles change when the particles are moved half as far apart one third as far apart?

HOW DOES THE MAGNITUDE OF THE ELECTRICAL FORCE BETWEEN A PAIR OF CHARGED PARTICLE WHEN THE PARTICLE ARE MOVED HALF AS FAR APART? … The force is reduced to 1/4 of its original value, no matter the sign of the original charges. Coulomb’s law defends our answer.

What factors affect electric force between two objects?

As we’ll discuss in this lesson, he found that the force between charged particles was dependent on only two factors: the distance between the particles and the amount of electric charge that they carried.

What is an attraction between electrically charged particles?

The attraction or repulsion between charged particles is called electric force. The strength of electric force depends on the amount of electric charge on the particles and the distance between them.

What causes electrical charges to attract and repel?

If a positive charge and a negative charge interact, their forces act in the same direction, from the positive to the negative charge. As a result opposite charges attract each other: The electric field and resulting forces produced by two electrical charges of opposite polarity. The two charges attract each other.

Do electrostatic charges attract or repel each other explain?

Attraction and repulsion of electric charges is one of three fundamental non-contact forces in nature. … Positive and negative charged objects attract or pull each other together, while similar charged objects (2 positives or 2 negatives) repel or push each other apart.

Do opposite charges attract or repel?

The electric field and resulting forces produced by two electrical charges of the same polarity. The two charges repel each other. … As a result opposite charges attract each other: The electric field and resulting forces produced by two electrical charges of opposite polarity.

What is the cause of static electricity?

Static electricity is created when positive and negative charges aren’t balanced. … When an object (or person) has extra electrons, it has a negative charge. Things with opposite charges are always attracted to each other, so positive charges seek negative ones and negative ones seek positives.

What makes a charged object attract an uncharged object?

When we put a charged object near an uncharged object, it produces opposite charges in the near end of the uncharged object by electric induction. … If we bring it near an uncharged sphere, the sphere forms negative charge near the glass rod, and positive charged on the end away from glass rod.

How does increasing the distance between charged objects affect the electric force between them?

How does increasing the distance between charged objects affect the electric force between them? The electric force decreases because the distance has an indirect relationship to the force.

Why is charge usually transferred by electrons?

Electrons are not affected by the strong force, and so they only get trapped by the electrical attraction to the nucleus which is much weaker in ionized atoms. Therefore it is easier for electrons to move away from one atom to another, transferring charge.

When you double the charge on only one of a pair of particles What effect does this have on the force?

The force will become four times stronger. This does not depend on the sign of the charges.
