Atoms and Nuclei question

2004 · Q135

NEETPhysicsAtoms and NucleiMCQ+4 / −1
If in a nuclear fusion process the masses of the fusing nuclei be m1 and m2 and the mass of the resultant nucleus be m3, then
  1. A
    m3 = m1 + m2
  2. B
    m3 = ∣m1−m2∣\left| {{m_1} - {m_2}} \right|∣m1​−m2​∣
  3. C
    m3 < (m1 + m2)
  4. D
    m3 > (m1 + m2)

Correct answer: C

In nuclear fusion the mass of end product or resultant is always less than the sum of initial product, the rest is liberated in the form of energy, like in Sun energy is liberated due to fusion of two hydrogen atoms.

As m1 + m2 = m3 + E

Since E = (m1 + m2 – m3) × c2
