- 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 5.0 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?(Express your answer in coulombs.) Part B: How strong is the electric field between the plates?(Express your answer in volts per meter.) Part C:If an electron is ejected at rest from the negative plates, how fast is it moving when it reaches the positive plate?(Express your answer in meters per second.)Suppose a swarm of bees flies through a thunderstorm and they become charged to –10.0 µC each.
