The density (in \(\mathrm{kg} \mathrm{m}^{-3}\) ) of nuclear matter is of the order of
- A \(10^{21}\)
- B \(10^{17}\)
- C \(10^{12}\)
- D \(10^8\)
Answer & Solution
Correct Answer
(B) \(10^{17}\)
Step-by-step Solution
Detailed explanation
\( \rho = \frac{m}{\frac{4}{3} \pi R_0^3} \) \( \rho \approx \frac{1.67 \times 10^{-27} \mathrm{kg}}{\frac{4}{3} \pi (1.2 \times 10^{-15} \mathrm{m})^3} \approx 2.3 \times 10^{17} \mathrm{kg} \mathrm{m}^{-3} \) Order of magnitude: \( 10^{17} \)
