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 1.7 × 10−¹⁴ m away from the gold nucleus? (e = 1.6 × 10−¹⁹ C,k_e = 8.99 × 10⁹ N·m²/C²) A)6.3E+1 N B)1.1E-12 N C)5.0E+3 N D)6.7E+6 N E)8.0E-5 N

The electrical force can be calculated using Coulomb's law: F = k_e * |q1 * q2| / r^2. Substituting the given values: F = (8.99 × 10^9 N·m^2/C^2) * |(-1.6 × 10^-19 C) * (79 * 1.6 × 10^-19 C)| / (1.7 × 10^-14 m)^2 = 6.3E+1 N.
