JEE Mains · Physics · STD 12 - 13. Nuclei
Mass numbers of two nuclei are in the ratio of \(4: 3\). Their nuclear densities will be in the ratio of
- A \(4: 3\)
- B \(\left(\frac{3}{4}\right)^{\frac{1}{3}}\)
- C \(1: 1\)
- D \(\left(\frac{4}{3}\right)^{\frac{1}{3}}\)
Answer & Solution
Correct Answer
(C) \(1: 1\)
Step-by-step Solution
Detailed explanation
Radius of nucleus \(R=R_{0} A^{\frac{1}{3}}\) Density of nucleus \(=\frac{\text { Mass of nucleus }}{\text { volume of nucleus }}\) \(\rho=\frac{ m \times A }{\frac{4}{3} \pi R ^{3}}\) Where \(m :\) mass of proton or neutron…
