In Rutherford's famous scattering experiments that led to the planetary model of the atom, alpha particles (having charges of +2e and masses of 6.64 x 10-27 kg) were fired toward a gold nucleus with charge +79e. An alpha particle, initially very far from the gold nucleus, is fired at 2.74 x 107 m/s directly toward the nucleus, as in the figure below. How close does the alpha particle get to the gold nucleus before turning around? Assume the gold nucleus...

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...
