प्रश्न
Draw a plot of potential energy between a pair of nucleons as a function of their separation. Mark the regions where potential energy is (i) positive and (ii) negative.
उत्तर
The potential energy is minimum at ro. For distances larger than ro the negative potential energy goes on decreasing and for the distances less than ro the negative potential energy decreases to zero and then becomes positive and increases abruptly.
Thus, A to B is the positive potential energy region and B to C is the negative potential energy region.
