Advanced Higher Physics Investigation

AI Thread Summary
The discussion revolves around finding alternative physics investigation topics for an Advanced Higher Physics course, as the initial idea of measuring the charge-to-mass ratio of an electron has been incorporated into the syllabus. Suggestions include exploring the Hall Effect and utilizing resources like Wikipedia for methods related to charge-to-mass measurements. Participants emphasize the importance of knowing the syllabus content to suggest relevant experiments. The need for three distinct experiments is highlighted, raising questions about whether they must be thematically related. Overall, the conversation seeks to identify feasible experimental topics within the constraints of the course.

As part of my Advanced Higher Physics course I am require to investigate an area of physics not covered by the syllabus. My first thought was to use telron tubes or similar in order to determine the charge to mass ratio of an electron. However it has just come to my attention that this has in fact been added to the course. Does anybody have any suggestions for similar areas of investigation?As far as I am aware I have to perform three different experiments and assosciated write ups.

Thanks in anticipation.

It would help to know what the syllabus/course does cover.
 
Well as far as I am aware the course covers the e/m determination using crossed fields. IF there were any other ways to find this then that would be great but I've yet to find any.

If you think you'd like to do charge-to-mass measurements, here's a place to start tracking methods down from: http://en.wikipedia.org/wiki/Charge-to-mass_ratio . Googling on

electron experiment "charge-to-mass ratio"

wll get you a ton of stuff, some of which has useful material on methods.

As for other areas of investigation, you could look at the Hall Effect. (I think I need to be more awake to come up with some other things you could try that could reasonably be done within a semester lab course.) Do all of your three experiments have to be on related themes? Is this largely an E&M lab course, or do you get into other branches of physics?

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
