Two objects that have an excess of one type of charge exert a force of repulsion on each other when relatively close together. Two objects that have excess opposite charges, one positively charged and the other negatively charged, attract each other when relatively near.
Why do forces 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.
Why do opposites charges attract?
Originally Answered: What makes the opposite charges to attract each other? The reason is stability or we can call it neutrality. Matter wants to possess neutral state. A negative charge wants to give away its electrons to become neutral therefore it attracts positive charge towards it.
What forces can either repel or attract?
A force that combines the effects of electrical charge and magnetism. The electromagnetic force can either attract or repel the particles on which it acts. Oppositely charged particles attract each other, while like particles repel one another.
Why do positive and positive charges repel?
Now, when a positive charge is brought closer to another positive charge, once the virtual transfer of photons occurs, there is an excess number of photons in both the charges, which tend to repel them away from each other. … Therefore, like charges repel and unlike charges attract.
Why do particles attract each other?
Answer: By an intermolecular force known as the intermolecular force of attraction, particles of matter are attracted to one another. In the three states of matter, the intermolecular force of attraction varies.
Is a positive force attractive or repulsive?
The Coulomb force between two or more charged bodies is the force between them due to Coulomb’s law. If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive.
Why do electrons repel each other?
When you have two electrons, the combined electric fields result in a higher and higher potential energy as they get closer. In order to minimize the potential energy, they repel each other (in the case of a positive and negative charge, potential energy is minimized by bringing them together, so they attract).
Do like charges attract or repel?
Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge.
Under what conditions do charges attract or repel each other?
Two like charges (positive or negative) repel each other and two unlike charges (one positive and one negative) always attract each other.
Why is attractive force negative?
You would have learnt this thing in chemistry (In Atom Structure, you would have calculated energy of electrons for different energy levels b/w electron & proton(nucleus)), that attractive force reduces the energy of the electrons and repulsive force increases the energy of electrons) So since energy corresponding to …
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 force attracts protons inside a nucleus to each other?
The strong nuclear force pulls together protons and neutrons in the nucleus. At very small distances only, such as those inside the nucleus, this strong force overcomes the electromagnetic force, and prevents the electrical repulsion of protons from blowing the nucleus apart.
Why do some ions attract while others repel?
Cations are positively charged and anions carry a negative charge. Ions form when atoms gain or lose electrons. … These oppositely charged ions attract each other to form ionic networks (or lattices). Electrostatics explains why this happens: opposite charges attract and like charges repel.
Why do atoms repel each other?
This tends not to happen, because atoms are composed of charged particles that interact at a distance. … Since the electrons are around the outside of the atom, those are the things that first interact, and as they have the same charge, they repel one another.
Why do electric field lines explain why like charges repel and opposite charges attract?
When charged particles are close enough to exert force on each other, their electric fields interact. The lines of force bend together when particles with different charges attract each other. The lines bend apart when particles with like charges repel each other.
