alleryAn atom bomb is based on which type of nuclear process?
AControlled chain reaction
BGamma decay only
CUncontrolled chain reaction
DBeta decay only
Answer & Solution
Correct answer: C. Uncontrolled chain reaction
1. In an atom bomb the number of neutrons multiplies without limit.
2. This is an uncontrolled chain reaction, releasing huge energy at once.
3. A controlled chain reaction (one neutron sustained) is used in a reactor, not a bomb.
