NEET PhysicsClass 12Alpha-particle scattering and Rutherford's nuclear modelMediumSingle correct

An alpha particle with kinetic energy 5.0 MeV heads directly towards a gold nucleus (Z = 79). How close does it get before stopping momentarily? (Take e²/4πε₀ = 1.44 MeV fm and ignore recoil of the nucleus.)
