Nucleus: Composition, Size & Nuclear Force question from JEE Main 2025 (8 Apr, Shift 2)

Q7JEE Main 2025 · 8 APR · SHIFT 2Easy

Nucleus: Composition, Size & Nuclear Force

For a nucleus of mass number A and radius R, the mass density of nucleus can be represented as

Show answer and solution

Answer: (b)

Mass $\propto A$ , volume $\frac{4}{3}\pi R_0^3 A \propto A$ .
Density $= \frac{\text{mass}}{\text{volume}}$ has no $A$ left.
So the answer is (b) independent of A.
