Questions
The fission of can be triggered by the absorption of a slow neutrons by a nucleus. Similarly, a slow proton cannot also be used. This statement is
a
Correct
b
Wrong
c
Information is insufficient
d
None of these
detailed solution
Correct option is A
Because the neutron has no electric charge, it experiences no electric repulsion from a U235 nucleus. Hence a slow-moving neutron can approach and enter a U235 nucleus, thereby providing the excitation needed to trigger fission. By contrast a slow-moving proton feels a strong repulsion from a U235 nucleus. It never gets close to the nucleus, so it cannot trigger fissionTalk to our academic expert!
