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 3.3 cm on a side, with a separation of about 5.3 mm . the plates are close enough that we can ignore fringing at the ends. part a under these conditions. how much charge is on each plate? part b how strong is the electric field between the plates? part c if an electron is ejected at rest from the negative plates, how fast is it moving when it reaches the positive plate?
