A gold foil of thickness 2.0 m is used in a Rutherford experiment to scatter particles

Question:

A gold foil of thickness 2.0 μm is used in a Rutherford experiment to scatter α particles with energy 7.0 MeV.

(a) What fraction of the particles will be scattered at angles greater than 90º?

(b) What fraction will be scattered at angles between 45º and 75º?
(c) Use N_A, ρ, and M for gold to compute the approximate radius of a gold atom. (For gold, ρ = 19.3 gm/cm³ and M = 197 gm/mol.)
