An ionized oxygen molecule (o2+) at point a has charge +e and moves at 1.92 ✕ 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 0.901 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 an oxygen molecule is 5.31 ✕ 10−26 kg and the fundamental charge is e = 1.60 ✕ 10−19 c.)\
