NEET Physics Nuclei Questions Solved


A nucleus with mass number A=240 and BE/A=7.6 MeV breaks into two fragments each of A=120 with BE/A=8.5MeV. Calculate the released energy.        (2)

Binding energy of nucleus with mass number 240,                    12


Binding energy of two fragments                                            12


Energy released =240(8.5-7.6)MeV                                        12


                         =216MeV                                                      12
