Which of the following the wrong description of the binding energy of the nucleus?
A. It is the energy required to break a nucleus into its constituent nucleons.
B. It is the energy made available when free nucleons combine to form a nucleus
C. It is the sum of the rest mass energies of its nucleons minus the rest mass energy of the nucleus.
D. It is the sum of kinetic energies of all the nucleons in the nucleus.
The correct answer is (d). All the other options are correct about binding energy per nucleon.
This is because inside the nucleus, the nucleons are in rest. So, there is no question of kinetic energy for those particles at rest.

Calculate the energy that can be obtained from 1 kg of water through the fusion reaction
2H + 2H →3H + p.
Assume that 1.5 × 10–2% of natural water is heavy water D2O (by number of molecules) and all the deuterium is used for fusion.

A nuclide 1 is said to be the mirror isobar of nuclide 2 if Z1 =N2 and Z2 =N1.
(a) What nuclide is a mirror isobar of?
(b) Which nuclide out of the two mirror isobars have greater binding energy and why?

The mass of a H-atom is less than the sum of the masses of a proton and electron. Why is this?Physics - Exemplar
Are the nucleons fundamental particles, or do they consist of still smaller parts? One way to find out is to probe a nucleon just as Rutherford probed an atom. What should be the kinetic energy of an electron for it to be able to probe a nucleon? Assume the diameter of a nucleon to be approximately 10–15 m.Physics - Exemplar
In pair annihilation, an electron and a positron destroy each other to produce gamma radiation. How is the momentum conserved?Physics - Exemplar
The binding energy of a H-atom, considering an electron moving around a fixed nuclei (proton), is . (m = electron mass). If one decides to work in a frame of reference where the electron is at rest, the proton would be moving around it. By similar arguments, the binding energy would be
(M = proton mass)
This last expression is not correct because
