The third of these nuclear interactions is the ‘weak’ force ; neither attractive nor repulsive , it acts inside the individual nucleons and can occasionally lead to a neutron’s transformation into a protonon (or vice versa), accompanied by a release of beta radiation.
Is weak force repulsive or attractive?
| Force Approximate Relative Strengths Attraction/Repulsion | Gravitational 10 − 38 attractive only | Electromagnetic 10 – 2 attractive and repulsive | Weak nuclear 10 – 13 attractive and repulsive | Strong nuclear 1 attractive and repulsive |

Are nuclear forces attractive or repulsive forces?
The nuclear force acts between all of the particles in the nucleus, i.e., between two neutrons, between two protons, and between a neutron and a proton. It is attractive in all cases . In contrast, an electrical force acts only between two protons and it is repulsive.
Is strong nuclear force always attractive?
Soon after Eugene Wigner explained the nuclei as a consequence of two different nuclear forces. The Strong Nuclear Force is an attractive force between protons and neutrons that keep the nucleus together and the Weak Nuclear Force is responsible for the radioactive decay of certain nuclei.
Is nuclear force repulsive?
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 .
Which is the strongest force in nature?
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 . Gravitation is by far the weakest of the four interactions at the atomic scale, where electromagnetic interactions dominate. But the idea that the weakness of gravity can easily be demonstrated by suspending a pin using a simple magnet (such as a refrigerator magnet) is fundamentally flawed.
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?
He pointed out that the fusion process in the sun, whereby hydrogen atoms glom onto one another to become helium , is an example of the weak force in action. A critical step in that reaction chain takes place through the weak force, so in fact the weak force drives the sun’s nuclear furnace.
What are the 4 types of forces?
fundamental force, also called fundamental interaction, in physics, any of the four basic forces— gravitational, electromagnetic, strong, and weak —that govern how objects or particles interact and how certain particles decay.
Which force has shortest range?
We should know that the strong nuclear force has the shortest range among all the four fundamental forces. The range of the strong nuclear force is 10 times shorter in order of magnitude.
What are the 2 types of nuclear forces?
The strong nuclear force pulled positively and negatively charged quarks together to form positively charged protons and neutrally charged neutrons. The strong nuclear force also binds protons and neutrons in the nucleus of atoms. The weak nuclear force enabled complex atoms to form through nuclear fusion.
Can electrostatic force be repulsive?
The electric force between charged bodies at rest is conventionally called electrostatic force or Coulomb force. ... If the charges have the same sign, the electrostatic force between them is repulsive ; if they have different signs, the force between them is attractive.
How strong is weak nuclear force?
The effectiveness of the weak interaction is confined to a distance range of 10 − 17 metre, about 1 percent of the diameter of a typical atomic nucleus. In radioactive decays the strength of the weak interaction is about 100,000 times less than the strength of the electromagnetic force .
Which force has an infinite range is always attractive?
The gravitational force acts between all objects that have mass. It always attracts objects together, and although it is the weakest of the four fundamental forces, gravity has an infinite range.
What are the four fundamental forces from weakest to strongest?
Actually, gravity is the weakest of the four fundamental forces. Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity.
