Hi i've attached the circuit as a word document, along with the question. I was not sure about the answers given, which I have copied below:

Between plates field is uniform
Acceleration is constant
Energy gained = 2000e where does 2000 come from, isnt it 4?
All ions have same F or same energy
From hole to detector is zero field/force
Ion travels at constant speed
g negligible - why?
time proportional to 1 /velocity how?
time proportional to 1 /mass how?
in a vacuum there are no collisions or friction forces
