The radius R of a nucleus is given by:
Correct answer: B. R=roA1/3
- A. R=roA-1/3
- B. R=roA1/3
- C. R=roA3
- D. None of these
Explanation
Correct Option: BThe radius of a nucleus can be approximated by the formula R = roA^(1/3), where ro is a constant and A represents the mass number of the nucleus. The mass number A corresponds to the total number of protons and neutrons in the nucleus.The formula suggests that the radius of a nucleus increases with the cube root of the mass number. This relationship arises from the idea that as the number of nucleons (protons and neutrons) increases, the overall size of the nucleus expands.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
