if the mass of two particals is 2 gms each then when they combine to form a nucleus hw much will be the mass of nucleus ?

Well, 2 + 2 = 4, the last time I checked.

However, you can't make an atomic nucleus out of two "particles" that massive

its given in question that keep in mind the topis mass defect and then i got the options

a) 4g
b) less thn 4g
c)more thn 4g
d)8g

To find the mass of the nucleus formed when two particles combine, you need to know the total mass of the particles before the combination and whether any mass is released or absorbed during the process.

In this case, you mentioned the mass of each particle is 2 grams, so the total mass of both particles is 2 + 2 = 4 grams.

If no mass is lost or gained during the combination process, then the mass of the nucleus formed will remain the same as the total mass of the particles before combination. Therefore, the mass of the nucleus would also be 4 grams.

However, it's important to note that in some nuclear reactions, mass may be converted into energy according to Einstein's famous equation E = mc^2, where E represents energy, m represents mass, and c represents the speed of light. In such cases, the mass of the nucleus might be slightly different from the sum of the individual masses of the particles.
