2fission in symmetric fission, the nucleus of uranium (238u) splits into two nuclei of palladium (1pd). to a rough approximation, the nuclei of heavy atoms may be described as spheres with a uniform charge density of 1.33 1025 c/m3. (this is a reasonable approximation, so far as their electrical structure is concerned.) the charge of the uranium nucleus is +94e. compute the initial electrostatic energy of the uranium nucleus and the electrostatic energy of the fission fragments once they have moved very far apart. you may ignore any interaction between the fission fragments. (a) how much energy is released by a single uranium nucleus in this process? give your result in both joules (j) and electron volts (ev) pd pd (b) how much energy would be released by symmetric fission of 1 g of 238u?
