This is a good question. You will need to think!

A very good question for the new syllabus!

Let me add just in case, you may make the assumption that the effect of gravity on the electron is negligible

Also typo. The time spent between the plates should be 2.6 times 10^{-9} in the 2nd last line!

Is it 0.10699m = 10.7cm? I'll give working if it's correct (tbh i'm not sure, I am bound to make a silly mistake somewhere even if I have the process right)

Thanks for bumping this thread, was going to answer Q2 but totally forgot about all it! Now there's a Q3 as well :)

I got a different answer for Q3, but will likewise post if I'm correct? I'm not too sure of myself because of the wordiness of the question, spent quite a bit of time just trying to understand what the question was asking :)

My answer7.2cm

Ye, I had a tough time visualising it hence why I am not sure it is correct. Hoping they give diagrams in the actual HSC.
