JEE Mains · Physics · STD 12 - 13. Nuclei
The ratio of the density of oxygen nucleus \(\left({ }_8^{16} O \right)\) and helium nucleus \(\left({ }_2^4 He \right)\) is
- A \(4:1\)
- B \(8:1\)
- C \(1:1\)
- D \(2:1\)
Answer & Solution
Correct Answer
(C) \(1:1\)
Step-by-step Solution
Detailed explanation
Nuclear density is independent of mass number As nuclear density \(=\frac{ Au }{\frac{4}{3} \pi R ^3}\) Also , \(R = R _0 A ^{\frac{1}{3}}\) And \(R ^3= R _0^3 A\) \(\Rightarrow\) Nuclear density \(=\frac{ Au }{\frac{4}{3} \pi R _0^3 A }\) Nuclear density…

JEE Mains 2016 Hard - The ratio of surface tensions of mercury and water is given to be \(7.5\) while the ratio of their densities is \(13.6\). Their contact angles, with glass, are close to \(135^o\) and \(0^o\), respectively. It is observed that mercury gets depressed by an amount \(h\) in a capillary tube of radius \(r_1\), while water rises by the same amount \(h\) in a capillary tube of radius \(r_2\). The ratio, \((r_1/r_2)\), is then close toJEE Mains 2019 Medium
