Which of the following figure represents the variation of In $\left(\frac{R}{R_{0}}\right)$ with $\ln A$ (If $R=$ radius of a nucleus and $A =$ its mass number)
$\pi $ mesons can be
Why do stable nuclei never have more protons than neutrons ?
How much is the Rutherford estimated the dimension of nucleus ?
The radius of a nucleus of mass number $64$ is $4.8$ fermi. Then the mass number of another nucleus having radius of $4$ fermi is $\frac{1000}{x}$, where $x$ is______.
If radius of the $^{27}_{13}Al$ nucleus is taken to be $R_{Al}$, then the radius of $^{125}_{53}Te$ nucleus is nearly
