Question

Use the following information to answer the next question. In the Rutherford alpha particle scattering experiment, some alpha particles were deflected coming straight back from the gold foil. When an alpha particle is emitted by the radium sample, it has a kinetic energy of 1.0 x 10-22 J. The electric potential energy of a charged particle in a radial electric field is modelled as kq192 Ер r Numerical Response 2. The maximum acceleration of an alpha particle at its closest approach to a nucleus of a gold atom, expressed in scientific notation, is a.b x 1000 m/s. The values of a, b, c and d are and (Record all four digits of your answer in the numerical response section on the answer sheet.)
