In a cathode-ray tube, a beam of electrons is projected horizontally with a speed of 9.6 X 10 8 cm/s into the region between a pair of horizontal plates 2.3 cm long. An electric field between the plates causes a constant downward acceleration of the electrons of magnitude 9.4 X 10 16 cm/s 2 Find (a) the time required for the electrons to pass through the plates, (b) the vertical displacement of the beam in passing through the plates, and (c) the horizontal and vertical components of the velocity of the beam as it emerges from the plates.
