In a head-on collision, an alpha particle (Z = 2) of energy 
bounces straight back from a nucleus of charge 
How close were the centers of the objects at closest approach? (1 eV = 1.60 × 10-19 J, e = 1.60 × 10-19 C, 1/4πε0 = 8.99 × 109 N ∙ m2/C2)
• 2.17 × 10-14 m
• 6.56 × 10-15 m
• 3.39 × 10-12 m
• 2.81 × 10-14 m

Thanks again.
