So Prof. P takes 2 handy metal plates and places them parallel to each other. He carefully adjusts them so they are 8.53 cm apart from each other and whips up a power supply to create a electric potential of 93 Volts between the plates. He notices there is a tiny hole on the positive plate so he decides to shoot a strangely handy electron straight through the hole at 3,950,851 m/s. Why? Who knows? How far in meters will the hapless electron travel from the positive plate until it stops?
