A particle accelerator fires an alpha particle, with a load of + 2e and mass ma = 6.64x10 ^ -27 kg, at 2x10 ^ 7 m / s directly towards the nucleus of an atom with a load of + 79e.
a) at what distance does the alpha particle approach before slowing down and being bounced?
b) In the attempt in which the alpha particle is still, how far from the nucleus is the total zero electric field?
consider both the alpha particle and the nucleus as conductive spheres and that are initially very far from each other

In Rutherford's scattering experiments, alpha particles (charge = +2e) were fired at a gold foil. Consider an alpha particle with an initial kinetic energy K heading directly for the nucleus of a gold atom (charge =+79e). The alpha particle will come to rest when all its initial kinetic energy has been converted to electrical potential energy. Find the distance of closest approach between the alpha particle and the gold nucleus for the case K = 3.0 MeV . (answer in...

In 1911, Ernest Rutherford and his assistants Geiger and Marsden conducted an experiment in which they scattered alpha particles (nuclei of helium atoms) from thin sheets of gold. An alpha particle, having charge +2e and mass 6.64 x 10-27 kg, is a product of certain radioactive decays. The results of the experiment led Rutherford to the idea that most of the atom’s mass is in a very small nucleus, with electrons in orbit around it. (This is the planetary classic...
