Solved: There are Z protons in the nucleus of an atom,
Chapter 30, Problem 30.49(choose chapter or problem)
There are Z protons in the nucleus of an atom, where Z is the atomic number of the element. An particle carries a charge of 2e. In a scattering experiment, an particle, heading directly toward a nucleus in a metal foil, will come to a halt when all the particles kinetic energy is converted to electric potential energy. In such a situation, how close will an particle with a kinetic energy of 5.0 1013 J come to a gold nucleus (Z 79)? * 6.
