JEE Mains · Physics · STD 12 - 13. Nuclei
Two nuclei of mass number \(3\) combine with another nucleus of mass number \(4\) to yield a nucleus of mass number \(10\). If the binding energy per nucleon for the mass numbers \(3\), \(4\) and \(10\) are \(5.6\) MeV, \(7.4\) MeV and \(6.1\) MeV, respectively, then in the process, \(\Delta Mc^2 = \) _____ MeV.
- A \(6.9\)
- B \(7.9\)
- C \(2.2\)
- D \(4.3\)
Answer & Solution
Correct Answer
(C) \(2.2\)
Step-by-step Solution
Detailed explanation
The nuclear reaction is given by: \(2 X^{3} + Y^{4} \rightarrow Z^{10}\) The total binding energy of the reactants is the sum of the binding energies of the two nuclei of mass number \(3\) and the nucleus of mass number \(4\). Binding energy of reactants…
