Question

Write two distinguishing features of nuclear forces.

Answer 1

Hint:Nuclear force is the strongest force in nature which acts between the two or more nucleons, it is million times stronger than the chemical binding force. In nuclear force the work is required to charge protons against the electric repulsion.

Complete step by step answer:
Nuclear forces are those forces which act between two nucleons.
In other words, we can also define nuclear forces as the force that is responsible for binding neutrons and protons in the same atom.
They are the forces essential for storing nuclear energy used in nuclear power and nuclear weapons.
The following characteristics of nuclear forces can lead us to the correct answer:
They are short range forces.
They are independent of charges.
Now, the two distinguishing feature of nuclear forces can be:
(i) They are short range forces: This means that the effect of such forces cannot be experienced beyond a certain range.
(ii) They are identical for all nucleons: This means that nuclear forces do not depend on the charge of the particle. For example: The force between two neutrons or between one proton and another neutron, all are equal in magnitude.

Additional Information: The nature of nuclear force is attractive in nature, although they have a repulsive core. This means that beyond a certain limit, the nucleons cannot come further close, as the force becomes repulsive. As discussed earlier, the nuclear energy stored is used in nuclear power and nuclear weapons is produced as the neutrons and protons bound together in an atom to form a nucleus. This force is responsible for storing energy.

Note: This nuclear force causes immense destruction in nuclear weapons. This occurs due to strong nuclear forces that releases high amounts of energy. In nuclear reactors, due to strong nuclear forces, energy can be produced. Neutrons can be transferred into a proton and vice versa due to weak nuclear forces.
