Chapter , Problem 5(choose chapter or problem)
There are Z protons in the nucleus of an atom, where Z is the atomic number of the element. An a particle carries a charge of 12e. In a scattering experiment, an a 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 a particle with a kinetic energy of 5.0 3 10213 J come to a gold nucleus (Z 5 79)?
