An alpha particle of kinetic energy 1.68 10-12 J is shot directly toward a platinum nucleus from a very large distance. What will be the distance of closest approach? The electric charge of the alpha particle is 2e and that of the platinum nucleus is 78e. Treat the alpha particle as a point particle, and the nucleus as a spherical charge distribution of radius 5.10 10-15 m, and disregard the motion of the nucleus.

Alpha particles which have a charge +2e and mass 6.64 x 10-27 kg are initially at rest and are fired directly at a stationary platinum nucleus (charge +78e) at a speed of 2.75 x 10 m/s. Determine the distance of closest approach (in fm) before the alpha particle reverses direction. Assume the platinum nucleus remains stationary. Assume the alpha particles are initially very far from a stationary platinum nucleus. fm

In a Rutherford scattering experiment, an α-particle (charge = +2.00e) heads directly toward a gold nucleus (charge = +79.0e). The α-particle had a kinetic energy of 7.95 MeV when very far (r → ∞) from the nucleus. Assuming the gold nucleus to be fixed in space, determine the distance of closest approach. (Hint: Use conservation of energy with PE=keq1q2/r).

If the alpha particles have an initial kinetic energy of 7.7 MeV, then assuming a head-collision between an alpha particle (helium nucleus with +2e charge) and a gold nucleus (79 protons, so +79e charge), and using conservation of energy at the point of closest approach when all of the alpha particle's kinetic energy is converted to electric potential energy, calculate the approximate distance of closest approach (and thus coarsely estimate the size of the nucleus)
