Consider the fission of a 92236U nucleus into two nearly equal spherical fragments 46118Pd and 46118Pd (neutrons ignored for this calculation).
(i) Calculate the radius of the parent 92236U nucleus.
(ii) Calculate the radius of each 46118Pd fragment.
(iii) Determine the total nuclear surface area before and after fission.
(iv) Find the percentage change in surface area produced by the fission process. Comment briefly on the physical significance of your result.
