The strong nuclear force is the force that holds protons and neutrons together. It also holds them all together in a nucleus and is responsible for the energy released in nuclear reactions, except for a much smaller portion due to the weak force, which is involved in beta decay.

What are properties of nuclear force?
Nuclear force is charge independent: The interaction between two nucleons is independent of whether one or both nucleons have a charge on them. In other words, the nuclear force between Proton-Proton (p-p)proton-neutron (p-n)and neutron -neutron (n-n)is the same, so these forces are charge independent.
Why is nuclear force the strongest force?
The strong nuclear force 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 (opens in new tab). And that’s because it binds the fundamental particles of matter (opens in new tab) together to form larger particles.
What is nuclear force Class 12?
Nuclear force is a force that acts between the protons and the neutrons of a nuclei. It is also called a force of attraction that holds the protons and neutrons in a nucleus together.
What causes nuclear force?
The strong nuclear force is created between nucleons by the exchange of particles called mesons. This exchange can be likened to constantly hitting a ping-pong ball or a tennis ball back and forth between two people.
What are the types of nuclear forces?
- A very strong short range attraction. The cohesion of the nuclear structure is mainly due to the attractive strong force, which is capable of overcoming the electrical repulsion the protons exert on each other.
- The electrical repulsion of protons.
- The tritium “weak decay”
What is the formula of nuclear force?
You can write down a two-particle force law for the strong force. It’s F=−V′(r) where V(r) is the function in Johannes’s answer.
What is the range of nuclear force?
The strong nuclear force is a very strong, attractive short-range (10-15 m) force that binds the protons and neutrons in the nuclei of atoms together. It is the strongest of the fundamental forces, but acts over a very short distance (10-15 m).
Are nuclear forces short range?
Reason: Nuclear forces operate over a very small distance i.e., 10 – 15 m or 1 fermi.
What is nuclear force example?
The most obvious example of Nuclear Force, as discussed earlier, is the binding of protons, which are repulsive in nature because of their positive charge. On a larger scale, this force is responsible for the immense destructive power of nuclear weapons.
What are the 4 nuclear forces?
In the same process physicists have uncovered four basic forces that act between these matter particles – gravitation, electromagnetism, the strong and the weak nuclear force. Only the first two can be directly seen in the macroscopic world so let us first describe them.
What are the 4 forces of the universe?
There are four fundamental forces at work in the universe: the strong force, the weak force, the electromagnetic force, and the gravitational force. They work over different ranges and have different strengths. Gravity is the weakest but it has an infinite range.
Who discovered nuclear force?
In 1935, the first theory for this new force was developed by the Japanese physicist Hideki Yukawa (Yukawa,1935), who suggested that the nucleons would exchange particles between each other and this mechanism would create the force.
What is weak nuclear force Class 11?
Weak nuclear force is the only force which does not follow parity-symmetry. It is the only force that does not follow charge-parity symmetry. Weak nuclear force is responsible for the change in quark into other forms. Carrier particles with significant masses are responsible for the propagation of the weak force.
What are nuclear forces and their properties Class 12?
Nuclear forces are attractive forces between proton and proton (P – P), proton and neutron (P – N) and neutron and neutron (N – N).
2. Nuclear forces are independent of charge. It was found that force between proton and proton is same as force between neutron and neutron.
Which force is strongest?
There are four fundamental forces: Gravitational force, Electromagnetic force, Weak nuclear force and Strong nuclear force. Among all these four forces, Strong nuclear force is the strongest.
Where does the strong nuclear force happen?
The strong nuclear force is one of four fundamental forces in nature. The strong force is ‘felt’ between nucleons (protons and neutrons) inside of the nucleus of an atom. The strong nuclear force is sometimes referred to as just the strong force or the strong interaction.
What are the two forces in the nucleus?
Holding the nucleus together There are two fundamental forces in the nucleus that aren’t observed outside of nuclei. These forces are creatively named the strong force and the weak force.
Is nuclear force a central force?
(3) Nuclear forces are the charge independent :- Nuclear forces acting between two protons , two neutrons and between a proton and neutron have same strength and the nature of force is attractive. (4) Nuclear forces are not central forces :- These forces do not obey inverse square law.
Is nuclear force charge dependent?
Nuclear Physics Nuclear forces are, to a high degree of accuracy, charge independent. That is to say, except for the explicit electromagnetic part, the neutron–neutron, neutron–proton, and proton–proton interactions are equal—when compared in the same state.
Is nuclear force a conservative force?
(ii) Weak forces and nuclear forces are non conservative forces.
Why nuclear forces are attractive?
The nuclear force is really attractive when the distance between two nucleons is around 1fm. As the distance increases beyond 2.5fm, this attractive force starts decreasing rapidly. Hence, for a medium to a large-sized nucleus, the forces get saturated leading to the constancy of the binding energy per nucleon.
Why nuclear force is called non central force?
Solution) Nuclear forces are called non-central forces because their direction does not depend upon the line joining the center of the subatomic particles. Q3) The nuclear force. (a) Obeys the inverse square law. (b) Varies inversely as the third power of the distance between the particles. (c) Is a short-range force.
Are nuclear forces strong between two protons?
The force between two protons is same as the force between proton and neutron and this force is a strong nuclear force- one of the four fundamental forces of nature. It is also the strongest force of the four.
Who discovered weak nuclear force?
In 1933, Enrico Fermi proposed the first theory of the weak interaction, known as Fermi’s interaction. He suggested that beta decay could be explained by a four-fermion interaction, involving a contact force with no range.
