Which of the following is a wrong description of binding energy of a nucleus?
It is the energy required to break a nucleus into its constituent nucleons.
It is the energy made available when free nucleons combine to form a nucleus.
It is the sum of the rest mass energies of its nucleons minus the rest mass energy of the nucleus.
It is the sum of the kinetic energy of all the nucleons in the nucleus.
It is the sum of the kinetic energies of all the nucleons present in the nucleus.
Binding energy of a nucleus is defined as the energy required to break the nucleus into its constituents. It is also measured as the Q-value of the breaking of nucleus, i.e. the difference between the rest energies of reactants (nucleus) and the products (nucleons) or the difference between the kinetic energies of the products and the reactants.
