In nuclear fusion process the masses of the fusing nuclei be m1 and m2 and the mass of the resultant nucleus be m3, then

1. m3 > (m1 + m2)
2. m3 = m1 + m2
3. m3 = |m1 − m2|
4. m3 < (m1 + m2)

Correct answer: m3 < (m1 + m2)

Solution

In a nuclear fusion process, some mass is converted into energy according to Einstein's mass-energy equivalence (E=mc²). Therefore, the mass of the resultant nucleus (m3) is less than the sum of the masses of the fusing nuclei (m1 + m2).
