A singly chalked oxygen molecule stare a free path in a direction at right angles to an electric field of intensity 10' V m-2. The pressure is one atmosphere and the temperature 300 K. (a) Compute the distance moved in the direction of the field in a time equal to that required to traverse one mean free path. (b) What is the ratio or the mean free path this distance? (c) What is the average speed in the direction or the field? (d) What is the ratio of the rms speed to this speed? (e) What is the ratio of the energy of thermal agitation to the energy gained from the field in one mean free path?
