In a cathode-ray tube, a beam of electrons is projected horizontally with a speed of 1.0x109 cm/s into a region between a pair of horizontal plates 2.0 cm long. an electric field between the plates causes a constant downward acceleration of the electrons of magnitude 1.0x1017 cm/s2. 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 components of the velocity of the beam is it emerges from the plates.
Answers: 1
is the initial vertical velocity
is the acceleration (negative because it is downward)
