The mass number of nucleus having radius equal to half of the radius of nucleus with mass number $192$ is:

A

$24$

B

$32$

C

$40$

D

$20$

(JEE MAIN-2024)

Solution

$R_1=\frac{R_2}{2}$

$R_0\left(A_1\right)^{1 / 3}=\frac{R_0}{2}\left(A_2\right)^{1 / 3}$

$A_1=\frac{1}{8} A_2$

$A_1=\frac{192}{8}=24$

The deuteron is bound by nuclear forces just as $H-$ atom is made up of $p$ and $e$ bound by electrostatic forces. If we consider the force between neutron and proton in deuteron as given 1 e 2 in the form of a Coulomb potential but with an effective charge $e' \,:\,F = \frac{1}{{4\pi { \in _0}}}\frac{{e{'^2}}}{r}$ . estimate the value of $(e'/e)$ given that the binding energy of a deuteron is $2.2\, MeV.$
