An Electron Is Sent at High Speed Toward a Gold

An electron is sent at high speed toward a gold nucleus (charge +79e) .What is the electrical force acting on the electron when it is 3.0 x 10^-14 m away from the gold nucleus? (e = 1.6 x 10^-19 C,k_e = 8.99 x 10⁹ N·m²/C²)

A) 20 N
B) 0.25 N
C) 2.0 x 10^-4 N
D) 2.1 x 10^-6 N
