# What is the gravitational force between a proton and electron?

## What is the gravitational force between a proton and electron?

The mass of an electron is 9.10938188 × 10-31 kg; the mass of a proton, 1.67262158 × 10-27 kg. The gravitational attraction then is 1.0167349 × 10-49 N, according to the law of gravitation.

## What is the gravitational force in the nucleus?

Gravitational force in the nucleus is so small because the mass of the particles that form the nucleus is small. There is little distance between objects in the nucleus, allowing the force to retain much of its strength, but the mass minimizes the amount of force that can be generated.

What force does a neutron apply inside the nucleus of an atom?

The strong nuclear force
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.

Do gravitational forces play a significant role in atomic structure?

Since the masses of an electron, proton, and neutron are small, the gravitational force between them is negligible and the gravitational force does not play a role in nuclear reactions or decays. The atom consists of protons, neutrons and electrons.

### How strong are electrical forces between an electron and a proton compared to gravitational forces?

Calculate the magnitude of the electric force between the electron and the proton in a hydrogen atom and compare this to the gravitational force between them. Discussion: As we can see, the electric force between an electron and a proton is 39 orders of magnitude larger than the gravitational force!

### How do you find the gravitational force of an electron?

All Answers (4) The gravitational attraction between two electrons is given by Gm2/r2, where G is the gravitational constant, m is the electron mass and r is the distance between the two electrons. The numerical value of the numerator is approximately 5.5 × 10−71.

Why is the gravitational force inside the nucleus so small?

Gravitational force in the nucleus is so small because the mass of the particles that form the nucleus is small.

What is the ratio of the strength of the gravitational force to that of the strong nuclear force?

Table 4.1 gives us comparison between the different fundamental forces. So the force of gravity is about ten to the minus 38, compared to the force of, the strong nuclear force, which is one. So the ratio is ten to the minus 38, the gravity is way way way smaller than the strong nuclear force.

## How strong is the strong nuclear force?

6 thousand trillion trillion trillion
The strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature. It’s 6 thousand trillion trillion trillion (that’s 39 zeroes after 6!) times stronger than the force of gravity, according to the HyperPhysics website.

## Which force is weakest force?

Gravity
Gravity. Gravitation is by far the weakest of the four interactions at the atomic scale, where electromagnetic interactions dominate.

Is there gravitational force in atom?

The atom is comprised of three major particles—protons, neutrons and electrons. There are four forces (Electromagnetic, Strong, Weak, and Gravity) that are responsible for the behavior of the particles and thus keep the atom together.

How does gravitational force affect an atom?

Gravity affects atoms the same way it affects all other matter. Every atom creates its own gravitational field which attracts all other matter in the universe. If you put a lot of atoms together, like in a planet or a star, all of the little gravitational fields add together, creating a much stronger pull.

### Where does the stability of the nucleus come from?

The stability of the nucleus comes from the operation of another type of force in the nucleus called nuclear force or strong force. 2. The force with which two protons, two neutrons, or a proton and a neutron, attract one another in the nucleus is called nuclear force (or strong force) .

### Which is the strongest force in the nucleus?

The Strong Force: As the name suggest, it is the strongest force known. It is so strong that it can hold two positively charged protons together in nucleus. But it has limitation to range. It can effect up to only 1 fm (femtometer or 10^-15 m).

Can a nuclear force cause attraction between a proton and a neutron?

Thus, the nuclear force can cause attraction even between a proton and another proton, even though they are similarly charged (both having positive charge). A nuclear force can also cause attraction between a proton and a neutron, as well as between a neutron and another neutron.

How does the nuclear force affect the nucleus?

The nuclear force acts on protons and neutrons and is universally attractive (protons and neutrons differ only in their electric charge which the nuclear force does not “see”). The strength of the nuclear force is about 100 times that of the electromagnetic repulsion between two protons, thus causing the atomic nucleus to stay together.
