A 6.0-cm-diameter, 11-cm-long cylinder contains 100 mg of oxygen (O2) at a pressure less than 1 atm. The cap on one end of the cylinder is held in place only by the pressure of the air. One day when the atmospheric pressure is 100 kPa, it takes a 177 N force to pull the cap off. What is the temperature of the gas?

An ionized oxygen molecule (O2+) at point a has a charge +e and moves at 2.00 x 10^3 m/s in the positive x-direction. A constant electric force in the negative x-direction slows the molecule to a stop a point B, a distance of 0.750 mm past A on the x-axis. Calculate (a) the x-component of the electric field and (b) the potential difference between points A and B.
