3. a) Alpha particles of the same initial speed are shot at the same intensity toward gold, silver, and aluminum foils of the same thickness. They are observed at a detector at a fixed scattering angle, 0 0°. What would the ratios of the number of alpha particles scattered by the gold and silver foils to the aluminum foil, Au NaAl Na Ag NaAl and respectively, be? (ZAu = 79, ZAg = 47, ZA1 = 13). b) Compare the number of a particles of fixed kinetic energy scattered through an angle of 10° (call this Na (10°)) with the number scattered through an angle of 20⁰ (Na (20°)) for Rutherford scattering by a thin gold foil of fixed thickness. Compute Na (10⁰) No (20°)* Rutherford's scattering model assumes that the alpha particles experience a Coulomb repulsion, F = KZe from the nucleus of the foil's atom. If, in a head-on collision the alpha particle has enough energy to get inside a uniformly charged KaZer nucleus of radius R, the force law would change to F and Rutherford's R³ " point-nucleus…
