Physics · Composition and size of nucleus, atomic masses, mass-energy relation, mass defect
Statement A: Density of nucleus is independent of its mass number Statement B: B
Statement A: Density of nucleus is independent of its mass number Statement B: Beryllium is used as a moderator in nuclear reactors
- A. Both A and B are correct
- B. Both A and B are wrong
- C. A is correct,B is wrong
- D. A is wrong,B is correct
Step-by-step solution
Statement A: Nuclear density is constant (≈ 2.3×10^17 kg/m^3) independent of mass number because volume is proportional to mass number. Statement B: Beryllium is used as a moderator in nuclear reactors to slow down neutrons.
