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. (C) Density of the nucleus is directly proportional to the 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.

  1. (A) and (D) only.
  2. (A) and (E) only.
  3. (B) and (E) only.
  4. (A) and (C) only.

Correct answer: (A) and (E) only.

Solution

The volume of the nucleus increases with mass number, supporting statement (A), while the density remains relatively constant regardless of mass number, which aligns with statement (E). Thus, both (A) and (E) are correct.
