List of top Physics Questions on Mass-Energy And Nuclear Binding Energy asked in UP Board XII

Explain the meaning of binding energy of a nucleus. Write the dependency of binding energy per nucleon on the mass number of the nucleus.
Explain the meaning of binding energy of a nucleus. In the nuclear reaction \(\ ^3Li^6 + \ ^0n^1 \longrightarrow \ ^2He^4 + \ ^1H^3 \), calculate the energy released in joules. Mass of \( \ ^3Li^6 = 6.015126~\text{u} \), Mass of \( \ ^2He^4 = 4.002604~\text{u} \), Mass of \( \ ^1H^3 = 3.016049~\text{u} \), Mass of \( \ ^0n^1 = 1.008665~\text{u} \), and 1u = 931 MeV.
What is the difference between nuclear fusion and nuclear fission? Find the value of the energy \( Q \) released with the help of the given nuclear fusion reaction:
\[ \text{1} \, ^1\text{H}_2 + \, ^1\text{H}_3 \rightarrow \, ^2\text{He}_4 + \, ^1\text{n}^1 + Q \] Given:
Mass of \( ^1\text{H}_2 = 2.0141 \, \text{amu} \)
Mass of \( ^1\text{H}_3 = 3.0160 \, \text{amu} \)
Mass of \( ^2\text{He}_4 = 4.0026 \, \text{amu} \)
Mass of \( ^1\text{n}^1 = 1.0087 \, \text{amu} \)
1 amu = 931 MeV
The binding energy per nucleon of \(\alpha\)-particle (\(_2^4\text{He}\)) is 7 MeV. What is its total binding energy?
