(a) Plot a graph showing the variation of potential energy of a pair of nucleons as a function of their separation. Also indicate the regions where the force is (i) attractive and (ii) repulsive.    

(b) Write two characteristic properties of nuclear force. 

 

 

Answers (1)

a) 

In the graph,

\Rightarrow For a separation greater than r_0, the force is attractive.

\Rightarrow For a separation less than r_0, the force is strongly repulsive.

b) CHARACTERISTIC PROPERTIES OF NUCLEAR FORCE:

\RightarrowThe nuclear force does not depend on the electric charge.

\Rightarrow The nuclear force between two nucleons falls rapidly to zero as their distance is more than a few fermenters.

\Rightarrow The nuclear force is much stronger than the Coulomb force acting between the charges or the gravitational forces between masses.
