# How does the strong nuclear force vary with distance?

## How does the strong nuclear force vary with distance?

The nuclear force is powerfully attractive between nucleons at distances of about 1 femtometre (fm, or 1.0 × 10−15 metres), but it rapidly decreases to insignificance at distances beyond about 2.5 fm. At distances less than 0.7 fm, the nuclear force becomes repulsive.

## What does strong nuclear force act on?

The strong force binds quarks together in clusters to make more-familiar subatomic particles, such as protons and neutrons. It also holds together the atomic nucleus and underlies interactions between all particles containing quarks.

Which acts over a longer distance the electrical force or the strong nuclear force?

Strong Nuclear Force A powerful force of attraction that acts only on the neutrons and protons in the nucleus, holding them together. Although this force acts over only extremely short distances, it is 100 times stronger than the electric force of repulsion at these distances.

### Which forces are the strongest at long distances?

In summary, gravity is the weakest of the forces in general, but it is the dominant one at astronomical scales because it has the longest range and because there is no negative mass.

### What is the weak nuclear force responsible for?

Weak interaction, also called weak force or weak nuclear force, a fundamental force of nature that underlies some forms of radioactivity, governs the decay of unstable subatomic particles such as mesons, and initiates the nuclear fusion reaction that fuels the Sun.

Which is the strongest nuclear force?

The proton and neutron, the only strong-force particles to have much of a permanent existence in our current world, are both baryons, with the quark configurations (uud) for the proton, with its electrical charge +1; and (udd) for the neutron, resulting in an overall neutral electric charge.

#### Which force works over a distance?

The SI unit of work is the joule (J), the same unit as for energy….Work (physics)

Work
A baseball pitcher does positive work on the ball by applying a force to it over the distance it moves while in his grip.
Common symbols W
SI unit joule (J)

#### What does the weak force attract?

The weak nuclear force is usually responsible for turning protons into neutrons or vice versa. It also applies to more exotic particles containing strange, charm, up and down quarks.

What is an example of a weak nuclear force?

The weak force, also called the weak nuclear interaction, is responsible for particle decay. This is the literal change of one type of subatomic particle into another. So, for example, a neutrino that strays close to a neutron can turn the neutron into a proton while the neutrino becomes an electron.

## How is the strong nuclear force able to work?

As long as this meson exchange can happen, the strong force is able to hold the participating nucleons together. The nucleons must be extremely close together in order for this exchange to happen.

## What are the carriers of the weak nuclear force?

The weak nuclear force is found to have three carrier particles, two W bosons, one charged -1 and one charged +1, and the electrically neutral Z boson. The W bosons have a mass of 80.22 GeV/(c squared), and the Z boson has a mass of 91.187 GeV(c squared).

How big is the range of the nuclear force?

The range over which this force acts is the size of an atom’s nucleus, which is about 10 -15 meter. The charge carriers associated with the strong nuclear force are called gluons. An easy way to remember this is to think ”gluons glue the nucleus of the atom together”.

### Which is stronger nuclear force or electromagnetic force?

The strong nuclear force is around 100 times stronger than the electromagnetic force. The range over which this force acts is the size of an atom’s nucleus, which is about 10 -15 meter. The charge carriers associated with the strong nuclear force are called gluons.
