[-/1 Points] DETAILS MY NOTES ASK YOUR TEACHER An ionized oxygen molecule (O, *) at point A has charge te and moves at 1.88 x 105 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 0.796 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 x 10 26 kg and the fundamental charge is e = 1.60 x 10-19 C.) HINT (a) the x-component of the electric field (in V/m) 4.0V V/m (b) the potential difference between points A and B (in V) Submit Answer [-/1 Points] DETAILS MY NOTES ASK YOUR TEACHER A constant electric field accelerates a proton from rest through a distance of 1.75 m to a speed of 2.17 x 105 m/s. (The mass and charge of a proton are mo = 1.67 x 10-2 kg and qp = e = 1.60 x 10-19 C.) HINT (a) Find the change in the proton's kinetic energy (in J). 4.0 (b) Find the change in the system's electric potential energy (in J). 40V (c) Calculate the magnitude of the electric field (in N/C). 4.0 N/C Submit
