Ques. 1JEE Main 2024, 27 January (Morning Shift)

In a nuclear fission process, a high mass nuclide (A 236) with binding energy 7.6 MeV/Nucleon dissociated into middle mass nuclides (A 118), having binding energy of 8.6 MeV/Nucleon. The energy released in the process would be MeV.

Answer

236

Solution

Q = (BE)products - (BE)reactant

= 2 118 8.6 - 236 7.6

= 236 (8.6 - 7.6) = 236 MeV

Answer: 236
