The radius R of a nucleus is given by
Correct answer: B. R= r0A"^/3
- A. R=r0A^-1/3
- B. R= r0A"^/3
- C. R= roA^3
- D. None of these
Explanation
Most nuclei are approximately spherical. The average radius of a nucleus with A nucleons is R = R0A1/3, where R0 = 1.2*1015 m. The volume of the nucleus is directly proportional to the total number of nucleons.

About Composition of Atomic Nuclei
Atomic nuclei contain positively charged protons and electrically neutral neutrons, collectively called nucleons. Questions use atomic number, mass number and nuclear notation to identify isotopes, isobars and isotones, and may connect nuclear composition with nuclear charge, mass defect, binding energy and the stability of the nucleus.
