Since, we know, the radius of a nucleus,

$R=R_0{\left(A\right)}^{\frac{1}{3}}$

Given,$A_{\mathrm{A}\mathrm{l}}=27$and$A_{\mathrm{T}\mathrm{e}}=125$

$\therefore \frac{R_1}{R_2}={\left(\frac{A_{\mathrm{A}\mathrm{l}}}{A_{\mathrm{T}\mathrm{e}}}\right)}^{\frac{1}{3}}={\left(\frac{27}{125}\right)}^{\frac{1}{3}}$

$\therefore R_2=\frac{5}{3}{R}_1$
