प्रश्न
Draw a plot of potential energy of a pair of nucleons as a function of their separations. Mark the regions where the nuclear force is (i) attractive and (ii) repulsive.
Draw a graph showing the variation of the potential energy of a pair of nucleons as a function of their separation. Indicate the region in which the nuclear force is (a) attractive and (b) repulsive.
उत्तर
The potential energy of a pair of nuclear as a function of their separation:
r0 is the distance at which potential energy is minimum.
For a separation greater than r0, the force is attractive and for separations less than r0 the force is strongly repulsive.
