In a nuclear fusion reaction, two nuclei, A and B fuse to produce a nucleus C, releasing an amount of energy \(\Delta E\) in the process. If the mass defects of the three nuclei are \(\Delta M_{A}\) , \(\Delta M_{B}\) and \(\Delta M_{C}\) - respectively, then which of the following relations holds? Here, c is the speed of light.
- \(\Delta M_{A}+\Delta M_{B}=\Delta M_{C}-\Delta E / c^{2}\)
- \(\Delta M_{A}+\Delta M_{B}=\Delta M_{C}+\Delta E / c^{2}\)
- \(\Delta M_{A}-\Delta M_{B}=\Delta M_{C}-\Delta E / c^{2}\)
- \(\Delta M_{A}-\Delta M_{B}=\Delta M_{C}+\Delta E / c^{2}\)
Answer
(B) M_ A + M_ B = M_ C + E / c^ 2
