Answer and Explanation: According to nuclear physics, a tensor force often implies a force dependent on a spin. This force is usually experienced between nucleons with similar interaction form between magnetic dipoles.

Why nuclear force is a tensor force?
The nuclear force also has a tensor component which depends on the interaction between the nucleon spins and the angular momentum of the nucleons, leading to deformation from a simple spherical shape.
What is a nuclear force simple definition?
Nuclear forces (also known as nuclear interactions or strong forces) are the forces that act between two or more nucleons. They bind protons and neutrons (“nucleons”) into atomic nuclei. The nuclear force is about 10 millions times stronger than the chemical binding that holds atoms together in molecules.
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 tensor quantity?
The magnitude, direction, and plane in which a quantity behaves or is defined in relation to its coordinate system are called tensor quantities. These are the quantities that are neither vector nor scalar.
What are the main features of nuclear force?
Solution : Important features (characteristics) of nuclear forces are given below :
(i) Nuclear forces are independent of charge.
(ii) Nuclear forces are strongest in nature and are about 100 times stronger than electrostatic forces.
What is definition of nucleon?
Definition of nucleon 1 : a proton or neutron especially in the atomic nucleus. 2 : a hypothetical single entity with one-half unit of isospin that can manifest itself as either a proton or a neutron.
What are nuclear forces 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 is the strong and weak nuclear force?
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. It was realized that the strength of the two forces differed a lot.
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.
What is magic number in nuclear physics?
Physicists refer to the number of protons or neutrons in a full shell as “magic” numbers, with numbers 2, 8, 20, 28, 50, 82, and 126 widely recognized as being “magic” numbers. The number of protons and neutrons also determines the size of an atom’s nucleus, called its charge radius.
What are the 4 forces?
Forces and carrier particles 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.
Which is strongest force in nature?
The strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature.
What force is alpha decay?
Alpha decay results from the Coulomb repulsion between the alpha particle and the rest of the nucleus, which both have a positive electric charge, but which is kept in check by the nuclear force.
What is tensor formula?
On components, the effect is to multiply the components of the two input tensors pairwise, i.e. If S is of type (l, k) and T is of type (n, m), then the tensor product S ⊗ T has type (l + n, k + m).
What is tensor example?
A tensor field has a tensor corresponding to each point space. An example is the stress on a material, such as a construction beam in a bridge. Other examples of tensors include the strain tensor, the conductivity tensor, and the inertia tensor.
What is tensor used for?
Tensors are a type of data structure used in linear algebra, and like vectors and matrices, you can calculate arithmetic operations with tensors. After completing this tutorial, you will know: That tensors are a generalization of matrices and are represented using n-dimensional arrays.
Is force a tensor?
For example: Force, Displacement, Velocity etc. Tensor quantities: When physical quantities are described with respect to a coordinate system then those quantities are called as tensor quantities or we can say that quantities which show some time vector properties and some time scalar properties.
Is pressure a tensor?
As pressure is a scalar quantity, so it is a zero-order tensor.
Why stresses are called tensor?
The restoring force per unit area is called stress. Stress has both magnitude and direction but it does not follow the vector law of addition thus, it is not a vector quantity. Instead, stress follows the coordinate transformation law of addition, and hence, stress is considered as a tensor quantity.
What are the two properties of strong nuclear force?
Properties of Strong Nuclear Force 137 times stronger than the electromagnetic force, 106 times stronger than the weak nuclear force, and 1.67 x 1038 times stronger than the gravitational force.
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).
Why nuclear force is saturated?
A nucleon interacts only with its nearest neighbouring nucleon. It does not interact with nucleons not in direct contact with it. That is why we say that nuclear forces show saturated effect. This is supported by the fact that binding energy per nucleon is same over a wide range of mass numbers.
Who discovered nucleons?
The atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on the 1909 Geiger–Marsden gold foil experiment.
What are the types of nucleons?
Primarily, there are two types of nucleons viz: protons and neutrons. A proton carries a positive electric charge, and a neutron has a neutral electric charge, which means that it bears no electric charge on it.
