The vertical deflecting plates of a typical classroom oscilloscope are a pair of parallel square metal plates carrying equal but opposite charges. The potential difference between the plates is 25.0 V. Typical dimensions are about 4.0 cm on a side, with a separation of about 5.0 mm. The plates are close enough that we can ignore fringing at the ends. Under these conditions:
(a) how much charge is on each plate, and
(b) How strong is the electric field between the plates?
(c) If an electron is ejected at rest from the negative plates, how fast is it moving when it reaches the positive p.
