5)An alpha particle is shot with a speed of \( 2 \times 10^{7} \mathrm{~m} / \mathrm{s} \) directly towards the nucleus of a gold atom. What is the distance of closest approach to the nucleus?(Take the mass of alpha particle \( =6.64 \times 10^{-25} \mathrm{~kg} \), charge on the alpha particle \( =3.2 \times 10^{-27} \mathrm{C} \), atomic number of \( \mathrm{Au}=79 \), while a proton charge \( = 1.6022 \times 10^{-13} \mathrm{C} \) )?
