A proton is travelling rightward between two parallel charged plates seperated by a distance d = 2.00 mm. The plate potentials are given as V1 = 20 Volt and V2 = 50 Volt. The proton consists of an initial speed of 100 km/s at the left plate.
a) Does the proton slow down or speed up?
b) Determine its speed just as it reaches the plate 2?
