Physics

Li2+ ion consists of a point-like nucleus of charge +3e and asingle electron whose average distance from the nucleus is 5 ́10-11 m. The electron kinetic energy is, on average, half as largeas the electric potential energy of the nucleus-electron system(ignoring signs). a) What is the value of the electric potential,due to the nucleus, at the location of the electron, when thelatter is at its average distance from the nucleus? b) What is theelectric potential energy (including sign) of the nucleus-electronsystem when the electron is at its average distance from thenucleus? c) How fast does the electron move when it’s at itsaverage distance from the nucleus? d) How much work is required (ofsome non-electric external force) to completely remove theelectron? e) If the electron were removed, how much work would theelectric field do during the removal process?
