The electrons that produce the picture in a tv set are accelerated by a very large electric force as they pass through a small region in the neck of the picture tube. this region is 1.5 cm in length, and the electrons enter with a speed of 1 × 105 m/s and leave with a speed of 2.5 × 106 m/s. what is their acceleration over this 1.5 cm length?
