An ionized oxygen molecule (O2^+) at point A has charge +e and moves at 1.68 ✕ 10^3 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. 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.)

(a) the x-component of the electric field (in V/m)

V/m

(b) the potential difference between points A and B (in V)
