प्रश्न
Which of the following statements about nuclear forces is not true?
पर्याय
The nuclear force between two nucleons falls rapidly to zero as their distance is more than a few femtometres.
The nuclear force is much weaker than the Coulomb force.
The force is attractive for distances larger than 0.8 fm and repulsive if they are separated by distances less than 0.8 fm.
The nuclear force between neutron-neutron, proton-neutron and proton-proton is approximately the same.
उत्तर
The nuclear force is much weaker than the Coulomb force.
Explanation:
As we know the nuclear force is a strong force, they are strongest in magnitude. They are short-range because the distance between the nucleon is 0.7 fermi which is very small.
They are charged independently. They result in the interaction of every nucleon with the nearest limited number of nuclear.
