An ionized nitrogen molecule (N2+) at point A has charge +e and moves at 1.68 ✕ 103 m/s in the positive x-direction. A constant electric force in the negative x-direction slows the molecule to a stop at point B, a distance of 0.841 mm past A on the x-axis. Calculate the x-component of the electric field and the potential difference between points A and B. (The mass of a nitrogen molecule is 4.65 ✕ 10−26 kg and the fundamental charge is e = 1.60 ✕ 10−19 C.)
