The masses of neutron, proton and deutron in amu are 1.00893, 1.00813 and 2.01473, respectively. The packing fraction of the deutron in amu is
- A \(11.65 \times 10^{-4}\)
- B \(23.5 \times 10^{-4}\)
- C \(33.5 \times 10^{-4}\)
- D \(47.15 \times 10^{-4}\)
Answer & Solution
Correct Answer
(A) \(11.65 \times 10^{-4}\)
Step-by-step Solution
Detailed explanation
\(m_n=1.00893, m_p=1.00813, m_d=201473\) Deuteron \(\left.{ }_1 \mathrm{H}^2\right)\) nucleus consist of one proton and one neutron. \(\begin{aligned} \therefore \text {Mass defect } & \Delta m=\left(m_n+m_p\right)-m_d \\ & =(1.00893+1.00813)-201473 \\ & =0.00233 \end{aligned}\)…
