Question

The density d of nuclear matter varies with nucleon number A as

• A. $d\alpha A^{2/3}$
• B. $d\alpha A^{1/3}$
• C. $d\alpha A$
• D. $d\alpha A^0$

Answer 1

The correct option is D

$d\alpha A^0$

$\text{density}=\frac{mA}{\left(\frac{4}{3}\pi R^3\right)}=\frac{3m}{\left(4\pi R_0^3\right)},m\to \text{mass of nucleon}$

Here, we have assumed that $m_{proton}\approx m_{neutron}=m$
