Answer 2

Hii friend,

# Atomic mass number-
The mass number is defined as the total number of protons and neutrons in an atom.

# Nuclear radius-
Radius of nucleus of an atom is called nuckear radius.

# Solution-
Nuclear radius is related to nuclear mass by following equation
$R = k{A}^ \frac{1}{3}$

For an atom with atomic radius R1 and atomic mass A1
$R1 = k{A1}^ \frac{1}{3}$
For an atom with atomic radius R2 and atomic mass A2
$R2 = k{A2}^ \frac{1}{3}$

Dividing (1) by (2)
$R1/R2 = {(A1/A2)}^ \frac{1}{3}$


Hope you understood everything
