How does distance between charged particles objects affect the electric force?

In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects.

What keeps electrons from drifting away from the nucleus in an atom?

The answer is electricity and magnetism. The atom’s center, or nucleus, is positively charged and the electrons that whirl around this nucleus are negatively charged, so they attract each other. The reason the force is strong is because the atom is so small.

For what order of distance is Coulomb’s law?

Coulomb’s law is true for all distances small and large. Hence it is called a long range force.

What is Sir Newton’s third law of motion?

Newton’s third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction.

What happens to the force between two charged metal spheres in a vacuum if the charge on each is doubled and the distance between them is multiplied by three?

The size of the force varies inversely as the square of the distance between the two charges. Therefore, if the distance between the two charges is doubled, the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value. The size of the force is proportional to the value of each charge.

What force holds electrons in atoms?

the electromagnetic force
Basically, it contains a nucleus, holding some number (call it N) of positively charged protons, which is surrounded by a cloud (N) of negatively charged electrons. The force that holds the electrons and protons together is the electromagnetic force.

What keeps atoms from collapsing?

The balance of kinetic and potential energy in an atom is what keeps its electrons from collapsing into the nucleus.

Is Coulomb’s law true for atomic distance?

Coulomb’s law is not true for nuclear size distance <10^-12m as when the distance is less than this the nuclear force dominates over electrostatic forces. Modern nuclear theory holds that nucleons (protons and neutrons) are held together within an atom’s nucleus by the presence of additional particles.

What does Coulomb’s law state?

According to Coulomb, the electric force for charges at rest has the following properties: Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The size of the force is proportional to the value of each charge.

Is there a vacuum between atoms?

If one equates space, with vacuum, then yes there is vacuum, not only between atoms, but within atoms themselves. In a single atom, the distance between the nucleus and the electrons in the lowest orbital (not orbit, electrons do not orbit the nucleus like planets) is immense.

Why is the space inside an atom empty?

’The space inside an atom is not empty in the sense you mean—it’s full of the electric fields of the protons and electrons and with the strong nuclear force holding the protons (and any neutrons) together.

Why does the temperature go up in a vacuum?

We didn’t say that temperature must go up in a vacuum. We just said that an ordinary vacuum can have a temperature due to the electromagnetic waves in it. That temperature will become the same as the temperature of the material surrounding the vacuum.

Can a vacuum have a temperature of zero?

So the answer really depends on what you mean by vacuum. If you mean what’s left when all the atoms etc. are pumped out, yes it still has a temperature of electromagnetic radiation. If you want, though, you could choose to only call that a vacuum if the temperature is zero.
