Question

The working principle of atom bomb is nuclear fission of uranium and the working principle of hydrogen bomb is:

  1. nuclear fusion of deuterium
  2. nuclear fission of thorium
  3. explosion of bomb involving hydrogen gas
  4. explosion involving dynamite and T.N.T.

Answer:

Option A: nuclear fusion of deuterium

Detailed Solution:

The correct answer is “nuclear fusion of deuterium”.

Atom bomb relies on nuclear fission, splitting heavy atoms (like uranium) to release energy.

A hydrogen bomb (or thermonuclear bomb) works on the principle of nuclear fusion, where isotopes of hydrogen, such as deuterium and tritium, are fused together at extremely high temperatures to release a massive amount of energy.
