An ionized oxygen molecule (0,+) at point A has charge +e and moves at 1.81 x 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 0.811 mm past A on the x-axis. The mass of an oxygen molecule is 5.31 x 10-26 kg and the fundamental charge is e = 1.602 × 10¬19 C.
