An Alpha Particle (Charge = +2e) Is Sent at High

Short Answer

An alpha particle (charge = +2e) is sent at high speed toward a gold nucleus (charge +79e). What is the electrical force acting on the alpha particle when it is at a distance of 2 × 10⁻¹⁴ m away from the gold nucleus? (e = 1.6 × 10⁻¹⁹ C)
