ન્યુકિલયસ $_{13}^{27}\,Al$ અને $_{52}^{125}\,Te$ ત્રિજયાનો ગુણોત્તર કેટલો થાય?
A
$6:10$
B
$13:52$
C
$40:177$
D
$14:7$
Solution
$r \propto {A^{1/3}}$
$\Rightarrow$ $\frac{{{r_1}}}{{{r_2}}} = {\left( {\frac{{{A_1}}}{{{A_2}}}} \right)^{1/3}} = {\left( {\frac{{27}}{{125}}} \right)^{1/3}} = \frac{8}{5} = \frac{6}{{10}}$
