An electron is a subatomic particle (m = 9.11 × 10^–31 kg) that is subject to electric forces. An electron moving in the +x direction accelerates from an initial velocity of +5.40 × 10⁵ m/s to a final velocity of +2.10 × 10⁶ m/s while traveling a distance of 0.038 m. The electron’s acceleration is due to two electric forces parallel to the x axis: ₁ = 17.50 × 10^–17 N, and ₂, which points in the –x direction. Find the magnitudes of

(a) The net force acting on the electron and

(b) The electric force ₂.
