= 3.824 * 10 FIsSION/SEU known that each 2U which undergoes fission releases 3 neutron and about 200 MeV of energy. Further (GATE Physics 2003) Example: An atomic bomb consisting of 235U explodes and releases an energy or 10" J. It is only 20% of the 235U atoms in the bomb undergoes fission : (ii) The mass of 235U in the bomb is about (A) 1.5 kg (B) 3.0 kg (C) 6.1 kg (D) 12 kg Please solve the 2nd part
