Question

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. $1: 1$
• C. $8: 1$
• D. $2: 1$

Answer 1

Answer: (B)

$1: 1$

Answer 2

Nuclear density is independent of mass number As nuclear density =34​πR3Au​
Also, R=R0​A31​
And R3=R03​A
⇒ Nuclear density =34​πR03​AAu​
Nuclear density =4πR03​3u​
⇒ Nuclear density is independent of A
