Neglecting Recoil of the Gold Nucleus,how Much Kinetic Energy Must

Neglecting recoil of the gold nucleus,how much kinetic energy must an alpha particle (charge =2 x 1.6 x 10^-19 C) have to approach to within 2.80 × 10−¹⁴ m of a gold nucleus (charge = 79 × 1.6 × 10−¹⁹ C) ? (k_e = 8.99 × 10⁹ N⋅m²/C² and 1 MeV = 1.6 × 10−¹³ J)

A) 9.03E-10 MeV
B) 4.64E+1 MeV
C) 4.06 MeV
D) 8.12 MeV
E) ​0.10 MeV
