જો $_{13}^{27}\,\,Al$ ની ત્રિજ્યા $3.6$ ફર્મીં હોય ત્યારે $_{52}^{125}\,\,Te$ ન્યુક્લિયસની ત્રિજ્યા ........ ફર્મીં થશે.

A

$6$ 

B

$8$ 

C

$4$

D

$5$ 

Solution

$  {\text{R}} = {{\text{R}}_{\text{0}}}{A^{1/3}}\,\,\,\, \Rightarrow \,\,\,\,\,3.6 = {R_0}{(27)^{1/3}}\,\,\,\,\,\,\,……(1)$

$  R = {R_0}{(125)^{1/3}}\,\,\,\,\,……(2) $

$  \frac{{3.6}}{R} = \left( {\frac{3}{5}} \right)\,\,\,\,\,$

$\therefore \,\,\,\,\,\,R = 6\,\,Fm $
