Nucleus: Composition, Size & Nuclear Force

Read the following statements:

(A) Volume of the nucleus is directly proportional to the mass number.

(B) Volume of the nucleus is independent of mass number.

(D) Density of the nucleus is directly proportional to the cube root of the mass number. (E) Density of the nucleus is independent of the mass number.

Choose the correct option from the following options.

Show answer and solution

Answer: (b)

$V \propto R^3 \propto A$ : (A) true, (B) false.
Mass $\propto A$ and $V \propto A$ , so density is independent of $A$ : (E) true, (C) and (D) false.
So the answer is (b) (A) and (E) only.
