The radius of a nucleus ofa mass number A is given by R=R_(0)A^(1//3) , where R_(0)=1.3xx10^(-15)m . Calculate the electrostatic potential energy between two equal nuclei produced in the fission of ._(92)^(238)U at the moment of their fission

Large angle scattering of alpha- particle led Rutherford to the discovery of atomic nucleus. It is the tiny central core of every atom in which entire positive charge of the atom is concentrated. The distance of closet approach of alpha particle from the nucleus is r_(theta)=((Ze)(2e))/(4pi epsilon_(theta)((1)/(2)mv^(2))) This distance r_(theta) gave him the order of size of nucleus. Read the above passage and answer the followign question: (i) What is the distance of closet approach of an alpha particle of energy 7.7 MeV from gold nucleus (z=79)? (ii) What is the implication of this relation in day to day life?

The radius of the nucleus ._(8)O^(16) is 3xx10^(-15)m . The density of this nucleus will be
