SATHEE: Nuclei - Result Question 1

Nuclei - Result Question 1

1. If radius of the $_{1} 2^{27} A l$ nucleus is taken to be $R_{A l}$ , then the radius of $_{5} 3^{125} T e$ nucleus is nearly:

[2015]

(a) $\frac{5}{3} R_{A l}$

(b) $\frac{3}{5} R_{A l}$

(d) $(\frac{53}{13})^{1 / 3} R_{A l}$

Show Answer

Solution:

(a) As we know, $R = R_{0} (A)^{1 / 3}$

where $A =$ mass number

$R_{A I} = R_{0} (27)^{1 / 3} = 3 R_{0}$

$R_{T e} = R_{0} (125)^{1 / 3} = 5 R_{0} = \frac{5}{3} R_{A I}$
