The vertical deflecting plates of a typical classroom are a pair of parallel square metal plates carrying equal but opposite charges. Potential difference between the plates is 25.0V; typical dimensions are about 3.8cm on a side with a separation of about 4.6mm. Under these conditions, how much charge is on each plate? How stron is the electric field between the plates? I fan electron is ejected from the negative plates, how fast is it moving when it reaches the postive plate?
