Q2 of 94 Page 440

Consider two pairs of neutrons. In each pair, the separation between the neutrons is the same. Can the force between the neutrons have different magnitudes for the two pairs?

The answer can be yes as well as no. The fact is that if the neutrons have the same spin, then the force will be of same magnitude (repulsive) and if they have opposite spin, then force will be of different magnitude(attractive). Such forces are often referred to as tensor forces.

If neutrons exert only attractive forces, why don’t we have a nucleus containing neutrons alone?

A molecule of hydrogen contains two protons and two electrons. The nuclear force between these two protons is always neglected while discussing the behavior of a hydrogen molecule. Why?

Is it easier to take out a nucleon (a)from carbon or from iron (b)from iron or from lead?

Suppose we have 12 protons and 12 neutrons. We can assemble them to form either a 24Mg nucleus or two 12C nuclei. In which of the two cases more energy will be liberated?
