Identify the correct statements.
(A) Neutrons penetrate the nucleus more readily as compared to protons.
(B) It is easier to release an orbital electron, but quite difficult to release a nucleon.
(C) Nuclear density is not the same for all nuclei.
(D) The radius of the nucleus is directly proportional to the cube root of the mass number.
Choose the correct answer from the options given below:
- A (A) and (B) only

- D (A) and (C) only
Answer & Solution
Correct Answer
(B) (A), (B) and (D) only
Step-by-step Solution
Detailed explanation
(A) Neutrons, being neutral, do not experience electrostatic repulsion from the positively charged nucleus and thus penetrate more readily than protons. (Correct) (B) Orbital electrons have binding energies in eV, while nucleons are bound by the strong nuclear force with MeV…
