The graph between $log\, R$ and $log\, A$ where $R$ is the nuclear radius and $A$ is the mass number is

A

B

C

D

Solution

(a) $R = {R_0}{A^{1/3}};$ where ${R_0} = 1.2 \times {10^{ – 15}}m.$

==> $log_e \,R = log_e\, R_0 + \frac{1}{3}{\log _e}A$

This is the equation of a straight line with positive slope.

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 $2.2\, MeV.$
